You can limit the amount of video RAM used by X using the VideoRam
directive in xorg.conf(5).
Ah okay. So now.. how do we do this for framebuffers?
Is it safe to poke around in radeon_identify_vram and maybe supply a kernel
argument videomem=32M and let it check, if it's bigger, then limit it, and
if not, keep the old size in rinfo->video_ram?
Can/could this be moved to all relevant framebuffer drivers?
GART doesn't have anything to do with this. I suspect he was thinking of
the PCI BARs not covering all video RAM.
That's certainly not the case here.
