Hi everyone,

I noticed a strange line in dmesg when KMS is enabled and I wondered how to 
get rid of it:

[drm:rs400_gart_adjust_size] *ERROR* Forcing to 32M GART size (because of ASIC 
bug ?)

KMS is very unstable for me and I feel like this error could be a reason.

This is the device in question:

I am using Kernel 2.6-git, mesa-git, libdrm-git and xf86-video-ati-git. Is 
there any way to fix this?
