I don't know if it helps, but IIRC the RadeOns (as well as Permedia3)
seem to use a different addressing-scheme which is only fully supported
on EV6 and up (at least that's what I think to have understood by
browsing through c.o.vms). I'm having an XP1000 w/ a RadeOn 7500 sitting
right beside me and no problems whatsoever with kernel 2.6.8 and 2.6.14.

On which card? The 9250? Do 325fps on the system mentioned above seem
