mtrr: 0xd8000000,0x2000000 overlaps existing 0xd8000000,0x800000
so it seems your card HW said it need 64M,
someone (BIOS or vgabios?) set 8M for it at first. and with write-back...
# cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1 reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1 reg02: base=0x100000000 (4096MB), size=1024MB: write-back, count=1 reg03: base=0xd8000000 (3456MB), size= 8MB: write-back, count=1
before loading X drivers, need to remove that entry at first.
echo "disable=3" > /proc/mtrr
