No noticeable difference here either.

I did notice a few compile errors though:
 r300 FP: Compiler Error:
 Fragment program does not support relative addressing  of source operands. 
 Using a dummy shader instead

And I'm getting these errors:
 radeon: The kernel rejected CS, see dmesg for more information.

dmesg:
 [340535.918564] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
 [340536.199125] [drm:r100_cs_track_check] *ERROR* [drm] Buffer too small for
color buffer 0 (need 4194304 have 3145728) !
 [340536.199129] [drm:r100_cs_track_check] *ERROR* [drm] color buffer 0 (1024 4
0 1024)

This behaviour is the same with or without the patch.
