+Initial Package Version: 6.13.2
+Upstream Status: Unknown, still applies in 6.14.
+Origin: Uncertain, I thought I found it included in cgit.freedesktop.org
+ on a stable branch of xf86-video-ati, but I had previously created my
+ own revert without the 'blames'.
+Description: Makes things 'just work' with my R200 (7500, 9200se) cards.
+(bug 32282 was mine, system unusable with the gimp's perspective tool).
+
+ This patch reverts:

+ RADEONPrepareAccess_CS: fallback to DFS when pixmap is in VRAM
+
+ This avoids costly CPU VRAM reads and lets EXA manage a system memory cache
+ of the portions of pixmaps needed for unaccelerated operations.
