hmm, you didn't turn on framebuffer devices by any chance?  by
accident?

Can you switch vga modes?  What happens if you pick another vga mode
(vga=ask in lilo.conf, then pick another video mode)?

If you reinstall/reboot into the old kernel, does the screen work as
expected? 

Which X server do you use?  Have you tried SVGA instead of the
accelerated server for S3?

The "previously working fine" sounds suspicious -- is the kernel
the only thing you've changed?  Eh, if it's the same version and
options, why did you recompile?
