xorg X11 using i81x drivers is very slow now! It does come up though!

It seems to be that the major fallout is with the screen not refreshing 
properly. If you go to the hat (or foot, with my theme), you only see 
the menu items if you hover the mouse over w/ the mouse button depressed.

There is a new patch submitted which is recorded from the first bug 
submitted by Mike. The patch is below. Why the i686 compilation worked 
and the binary rpm version on cvs did not is beyond me.

My interrupts seem to be pretty much ordinary. I hope the new patch 
works better. mtrr usually adds the last line to the file. With the 
rawhide version binary driver, the last line is never added (reg02)

cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size= 512MB: write-back, count=1
reg01: base=0x1ff00000 ( 511MB), size=   1MB: uncachable, count=1
reg02: base=0xf8000000 (3968MB), size=  64MB: write-combining, count=1

I have a screenshot of the resulting screen attached to the bug report.

The patch is in the below bug report.
