DRM & X.Org 6.8.0 oops

[Mihai Rusu]

Hi

There seems to be some DRM problem with X.Org 6.8.0 on 2.6.8.1. I recently 
switched from XFree86 and there I did not noticed the same thing.

System information: P4 2.8 Ghz HT, Intel 865G on-board graphics, ASUS 
P4-P800VM mobo, having compiled preempt, SMP (for HT, which works) and SMT 
scheduler.

It seems to happen when starting xdm/gdm.

ksymoops parsed kernel message:
mtrr: base(0xf0020000) is not aligned on a size(0x400000) boundary
[drm:i830_dma_initialize] *ERROR* can not find dma buffer map!
