first of all you'd add 3 overlays:

the first one will be your personal overlay (since you'll need some modified
ebuilds and you'd want to put them there instead of modifying them all the
time in their original overlay).
you'll add the following directory as root: mkdir -p
/var/portage/personal-overlay and then assign it to portage: chown
portage:portage /var/portage/ -R

now you'll install layman (if you already don't have it): emerge layman
then go and edit the file /etc/layman/layman.cfg by pointing the storage to
this directory:

#-----------------------------------------------------------
# Defines the directory where overlays should be installed

storage   : /var/portage/layman


then you'll do a layman -a desktop-effects to add the first overlay
and layman -a x11
if one of them would fail then you should fetch the list of repos with
layman -f and add it again. it should work at that time.
you also should sync these 2 overlays once a week with layman -s.

then you go and edit /etc/make.conf to add the new layman repos and the
personal overlay by adding the following lines:

source /var/portage/layman/make.conf
PORTDIR_OVERLAY="/var/portage/personal-overlay"

the next step is to configure the various options of layman repos by editing
/var/portage/layman/make.conf.

and assure that the directories in which you've fetched the overlays are
listed here.
you should have the 2 directories (/var/portage/layman/x11 and
/var/portage/layman/desktop-effects) listed here.

now you have to unmask the packages you want to install by adding the
keyword and then unmask them in portage.
for the desktop-effects overlay you don't have much trouble cause there's a
good documentation in the /var/portage/layman/desktop-effects/Documentation
directory. you already have keywords and unmasks set there as a set to
install compiz-fusion.

you take the x11.tar.gz in attachment and uncompress it in the x11 overlay.
you have some files there:
in the Documentation directory you have the keywords for the packages and
the unmask of the packages you want to install while in the sets directory
you have some sets for the various stuff you'll need to install (x11-protos
x11-libs x11-base). you copy the keyword and unmask files in the portage
conf dir and then you can go and prepare the ebuilds in your personal
overlay.
you take the x11-drivers.tar.gz and extract it in the personal overlay.

now, before compiling the new server you have to recompile your kernel. i
assume you use the 2.6.26 kernel (i haven't yet tested this in the r1
release).
you have to apply this patch
http://people.freedesktop.org/~keithp/gem_patches/0001-Export-shmem_file_setup-for-DRM-GEM.patch<http://people.freedesktop.org/%7Ekeithp/gem_patches/0001-Export-shmem_file_setup-for-DRM-GEM.patch>
on the kernel with patch -p1 < <location of saved patch file>/patch file
after you go to the /usr/src/linux directory.

after that you might start compiling the x11 live packages by starting with
the x11-protos, then going with x11-libs and then x11-base. you might need
to keyword or unmask some other packages around and just do that if
something needs them. you might also have some fails on some ebuilds. the
following ebuilds are known to fail:
libXaw might fail; cairo and glitz probably fail due to some autoconf issues
(i don't know why but in the past they used to work then started not working
anymore), libxcb will surely fail and you might need to remove the installed
one before installing the new one. this approach works fine with all the
packages that fail for the missing libxcb-xlib.la file in the new libxcb.
after you've finished installing the xorg-server then you need to install
the drivers (you're almost there). first install the following:
xf86-input-keyboard xf86-input-mouse xf86-input-evdev xf86-video-ati (if the
new xorg-server hasn't yet pushed them in). now the synaptics driver doesn't
build anymore and i'm still struggling with it. for the moment you'll need
to use the xf86-input-synaptics driver, instead (the one in the personal
overlay).

the last attachment is the xorg.conf for use with xf86-video-ati driver.

sorry for the delay but it took me some time to write down everything.

for the compile into ram stuff i'll post the next time or you could follow
the instruction from gentoo wiki. the basis is that you'll point the
/var/tmp/portage folder to /tmp. i personally do this in /etc/local where i
create a folder in /tmp, i assign it the tmpfs permissions (chmod 1777) then
i mount in bind this folder to /var/tmp/portage.
the problem is that when mounting /tmp in fstab you'll need some tweaks on
the tmp dimension and you'll need to look out into your ram space and swap
space to see how to set this.
