Yep, looking good on an X850XT:

Anything else needed or is that enough? I've only tried the X850 out of all of
my cards, as only this machine has a -CURRENT installed. Also hanging around
are the Xpress 200 (which doesn't show MSI support in pciconf -lvc so I think
it may be a pointless exercise), a 9200 and a 9700Pro. If you think it's worth
it, I'll set up a -CURRENT on the AGP box and test these.
Sorry for the delay. I had to set up -CURRENT on this box as it looks like it
will be handy to test these Radeons from time to time.
