My posting to the X.org mailing list can be found here: http://lists.freedesktop.org/archives/xorg/2006-October/018679.html I get the following warnings once my X server starts: mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000 In Xorg.0.log I get these warnings: (WW) RADEON(0): DRI init changed memory map, adjusting ...
