after apply simple patch to XFree86 4.3.0:


--- neo_driver.c	Sun Apr 13 11:51:56 2003
+++ neo_driver.c	Sun Apr 13 11:41:27 2003

 	}
     }
 
+    VGAwGR(0x93,0xc0); /* Gives faster framebuffer writes */
+
     /* Program vertical extension register */
     if (nPtr->NeoChipset == NM2200 || nPtr->NeoChipset == NM2230
 	|| nPtr->NeoChipset == NM2360 || nPtr->NeoChipset == NM2380) {



all framebuffer operations speedup about 4 times

for example:


xengine 		1000rpm -> 3300rpm
glxgears 		72fps   -> 127fps
Xv (VO with DVD)  	+100%   -> 25% (!!!)



this info (and patch) shoud be included somewhere in DOCS (instead info
of binary driver - 4.3.0 already have Xv)

best regards
