Sounds decent.  I'd be extremely reluctant to update FC5 to something
that's only in CVS.  The only reason for suggesting it is that it seemed
like you were saying that some people were seeing lockups even with
the r300 dri driver from Mesa not even present on their system.  Maybe
I misread it, but if it turns out that there's no other way to prevent
hangs on r300-based cards then the CVS patches should perhaps be considered.

Note that some of the bug reports claim that even without DRI lockups
occur from using the framebuffer device, and that a lot of the patches
apply to the main radeon X driver rather than dri.  I don't know if
removing the dri driver is enough to fix it.  Hopefully so.
