Open-Source ATI R500 EXA & XAA Support

What's the syntax for the

XAANoOffscreenPixmaps

option? Is it:

Option "XAANoOffscreenPixmaps" "enable"

Option "XAANoOffscreenPixmaps" "true" but also enable should work. look into the xorg log and see if it skips the option or not. if it is not skipped then the syntax is correct.

Tks. Subjectively, enabling that makes things noticeably faster.

Here's some informal GTKperf results (default settings), radeonHD (latest from git), ATI X1950XTX, Intel Core2Duo E6600, Ubuntu 7.10:

ShadowFB 6.02
XAA (XAANoOffscreenPixmmaps) 11.7
XAA 17.74

I don't know if it's always been like this, but latest driver from git with "AccelMethod" "EXA" added, cripples my computer to the max.
