w00t!

Xenhide still may not do the trick in your case. It will prevent Windows
from seeing the device, but the tap device will still be there and
attached to the bridge, which may cause problems of its own...

I have a scsiport driver working nicely now... almost... it crashes
occasionally and of course it won't write out a crash dump for me :)
