I'd suggest filing a bug in bugzilla.  Please indicate which driver 
you're using (see glxinfo).  Maybe one of the ATI developers will be 
able to help you.

OK Brian,

I'll do that

Brian,*
*
I filled-up a bug - here is the link*
*http://bugs.freedesktop.org/show_bug.cgi?id=17957

The amazing thing is that there is a quite similar bug filled-up 3 years ago
and still unassigned.

I truly hope that this one will be luckier. I'm ready for a release (toped),
but this is really stopping me, because my packages on fc9 will not be fully
functional. It seems that all distros are affected, but fc9 currently has to
stick to DRI drives and Mesa for ATI. There is no alternative there.

I'll appreciate your help! Even if it is simply a link to appropriate
people...

Regards
Svilen

You're probably most likely to get help by posting to the mesa3d-dev 
list and hoping one of the r300 developers can help you.  I don't have a 
r300 card.
