I found a posting on x11@ by Jung-uk Kim about testing AGP before blaming DRI. I compiled the program and ran it, here is what I am getting: version: 0.0 bridge id: 0x7551039 agp_mode: 0x1f000217 aper_base: 0xe8000000 aper_size: 4 pg_total: 112640 pg_system: 112640 pg_used: 0 MTRR: e8000000/400000 entry.key : 4 ioctl(AGPIOC_BIND): Invalid argument Apparently, the aperture is being incorrectly probed as 4M. I have it at the smallest setting which is 32M. Is there something I can do to force it to the correct amount of memory?
