Building KMS related drivers in the kernel as opposed to selecting
them as modules and removing framebuffer modules may also address the
OP's problem (which I suspect is caused because KMS has not loaded
*before* xorg starts).

Hmm ... unless this USE flag shows up in later versions or overlays,
only radeon is available for mesa-7.9

# emerge -1aDv mesa

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] media-libs/mesa-7.9  USE="classic gallium nptl -debug
-gles -llvm -motif -pic (-selinux)" VIDEO_CARDS="radeon -intel -mach64
-mga -nouveau -r128 -savage -sis -tdfx -via -vmware" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB

Would you like to merge these packages? [Yes/No] No

Quitting.
