I've patched my i830_video.c file to have the 1088 value, but I still  
don't seem to have the CacheLines/LinearAlloc values right, as  
1920x1080 (or rather, 1088) video still won't play. Even 8192  
linearalloc doesn't seem to help and actually causes X to fail to load.

I am using i810 1.6.5.

Suggestions for the correct values?
