This bug was posted to the XFree86 mailing list today by someone running
Debian unstable and a Radeon 9000. I'm running RH 8.0, XFree86 4.3.0 and
GNOME 2.2.1 with a Radeon 7500 and it suffers from this problem. It
appears to be just a typo in radeon_cursor.c.
The patch attached was posted to the mailing list. I modified it work
with the Red Hat SRPM. I'm recompiling X right now to see if this fixes
the problem.
You will have to install the XFree86 SRPM, place this patch in (if you
are rebuilding as root) /usr/src/redhat/SOURCES, and modify the .spec
file to apply the patch. If you don't know how to modify the .spec file,
e-mail it to me and I will edit it and send it back. I don't have RH 9
so I can't just send you an already compiled module. You will have to
recompile the SRPM.
