I think any multi-threaded OpenGL-app should trigger "my"
bug if it draws enough (more than a cube).
disabling VTXFMT helps: no lockups anymore, everything works fine,
but I have to disable SSE, too,
otherwise I would get a sigfpe on my athlonXP1700+
FWIW, I get those SSE sigfpe's too with my Northwood P4 if I don't set
MESA_NO_SSE=1.
There's a fix for this in recent cvs:
/* Mask out highest bit, which is used by AMD for 3dnow
* Newer Intel have this bit set, but do not support 3dnow
*/
AND_L ( CONST(0X7FFFFFFF), EAX)
