Assume you using genkernel without any modifications to kernel config?
Got interested why this doesn't work with KDM so here it is:
...BEGIN...
#emerge kdm -pv

These are the packages that I would merge, in order:

Do you have "opengl" in your USE-flags (in "/etc/make.conf" file)?
If Yes this could explain why login fails only with KDM. Could be wrong here though ;-)
Solutions:
1.compile a new kernel with AGP support in it (see above in kernel config) or
2.remove 'opengl' from "make.conf" and rebuild all affected packages (emerge -N world -pv).
