That's actually the first I've heard of that problem.  I don't see why
it wouldn't still be the case, fglrx is broken if that report is
accurate.

I'm not a good example, I don't do anything on the host VGA at all.

If you plan to run fglrx in the host, it would certainly help to work
around the above issue, but I don't have much direct experience with
anything newer than an 8400GS.

Yep, I'm astonished at the number of users trying to make this work.
I'm sure someone has some knowledge they can share.  Thanks,

Alex
