The rsync of atimach64ppc.c I got earlier today doesn't have this
unconditonal assignment hack anymore.  The hardwired vram setting

It was too obvious to go undetected for long :-). Now if the kernel
framebuffer driver (atyfb, and don't check the 'no video driver' option
when using BootX) reportds the correct vram size the X server should see
the correct size as well.

However, I see a problem. Atyfb reports the video RAM size minus the cursor
area. If you divide that number of bytes by 1024 to get pScrn->videoRam, you
end up with 1 MB too few :-(

  Hmm does this mean that mmapping the framebuffer doesn't give you the
start of vram but vram+offset ? if yes then we have a big problem here.

BTW you'll end up 1KB too few not 1MB, pScrn->videoRam is in KBytes :)
