I've managed to use the new embedded-stage1 from Gentoo to compile
myself a basic system, which is at least what buildroot does plus lots
of more apps. I've even managed to compile xorg (6.8.0-r4 was the only
one that worked for me right out of the box, it's currently masked).

Try to use Gentoo, it really works quite well. I've managed to compile
samba (even the server) and ntfsprogs with the default ebuilds. The NFS
support mentioned in the subject relies on the kernel as said in recent
thread here ("can't emerge nfs-utils") but can work, too. Userspace NFS
doesn't seem to work yet because of not-glibc-like rpc support in
uclibc.

Yes, you've got a lot more build scripts. If they work is another
question. And I personally found it easier to use Gentoo for all this.
When building your final filesystem, you should make a copy of the build
system and delete everything that isn't needed. You can, on the other
hand, build packages when emerging and then use "ROOT=/your/target/root
emerge -K package" for everything you need.

A last tip: I wouldn't recommend to actually install busybox into your
dev environment. Just emerge it with "emerge --buildpkgonly busybox" and
then do a "ROOT=/your/target/root emerge -K busybox"

Note that gentoo won't work as a cross compilation env, AFAIK.
