A similar problem that you describe I experience when my Radeon 7500
sits in a K6-2 machine. The image of the mouse pointer, KDE title bars
and default background are garbled. When running twm, only the mouse
pointer image is garbled.

When running in a K7 machine (XP 2400+) with the identical
setup, the card works flawlessly in either 1- or 2- head setup,
and in the latter with either Xinerama enabled (one extended
screen on two monitors) or disabled (two screens, one on each
monitor).

Perhaps someone intimately familiar with the architecture could
explain what is the cause of the problem.

Tested using XFree86 Version 4.3.0 on NetBSD/i386 1.6Q and
NetBSD 1.6ZD.

The only eye-catching part in the K7's log file is the following:
