Text drawing problems on armbe-linux platform with sisusb driver

[George McCollister]

I'm having trouble with text drawing in X on an ARM (XScale) Linux 2.6.x 
big endian platform using the sisusb driver. Text is drawn, but it is 
always ~20 pixels to the right of where it should be. All X applications 
including xterm, xfontsel, xcalc and xgc have the problem. The problem 
also happens regardless of which font or type of font is being used.

The same source tree with the same configuration on a powerpc (also big 
endian) Linux 2.6.x platform with the same X driver (and sisusb kernel 
driver) works fine. I was originally experiencing the problem with 
6.9.0, but I finally got the GIT tree cross compiling and it is having 
the same issue.

When building in 6.9.0, I was using all of the libraries included in 
xc/extras so I don't believe the problems stems from an incompatible 
library version.

This is a link to a picture I took after running “startx”.

Does anyone have any idea which library or portion of X might be causing 
this problem. If I have some idea of where the problem is occurring I 
can probably fix the problem and post a patch. Any and all suggestions 
are much appreciated.

If anyone would like me to provide more information please let me know.
