[gentoo-user] Kernel Linux 2.6.25-r7 with gentoo patches fail to boot

Good afternoon,
I have used my weekend to compile a new kernel, but to my dismay the new
kernel does not boot. All I get is a black screen, and nothing happens.
I compiled the kernel like this:
eselect kernel set (the new sources)
cd /usr/src/linux
make oldconfig
(answering various options about new features)
make menuconfig (haven't changed much, only made sure that all the modules I
new were necessary were included).
make && make modules_install
mount /boot
copied the kernel, reconfigurated grub, and rebooted.

So, probably, I have set something in kernel incredibly wrong, but I don't
know what, or how to find out. My last working kernel is 2.6.25-r7:
yoav@yoavhost ~ $ uname -a
Linux yoavhost 2.6.25-gentoo-r6 #1 SMP Sat Jul 5 22:33:03 IDT 2008 x86_64
AMD Athlon(tm) 64 X2 Dual Core Processor 4000+ AuthenticAMD GNU/Linux

how can I find out what I did wrong?

You forgot to copy your current configuration.  *Before* doing "make 
oldconfig" you to either do:

   zcat /proc/config.gz > .config

or:

   cp ../linux-yourpreviouskernel/.config .

and *then* run "make oldconfig"

You can also emerge debianutils (I think it's installed by default, but 
check first) which will enable you to do a "make install" instead of 
copying the files by hand to /boot.  It will name the files correctly 
(vmlinuz symlink to vmlinuz-version along with System.map and config).
