The screenshot you attached to the original report shows unaligned
accesses as well. Are you saying those no longer occur with your
self-built r300g?
Anyway, it would be great if you could report this upstream at
http://bugs.freedesktop.org/enter_bug.cgi?product=Mesa , component
Drivers/Gallium/r300. The main upstream r300g developer (Marek Olšák) is
usually quite responsive to bug reports.
