Hi Roger, thanks for following up. I will try this tomorrow and mail the
results.

Also, for the sake of being as thourough as possible -- just now I sent
a bug report about HVM issues. This is occurring on the same machine
but I also had HVM problems when it was still running ArchLinux. So I
doubt those are related but I want to make sure people know this
regards the same machine.
