Ow, that really does qualify as a dirty hack. :) Thanks for finding
that! I currently don't have the time to skim through pages of code, so
sorry for my non-involvement on this issue...

Yesno. It does (at least kvm does not crash), but it shows the same
dialog problems as reported by Leslie:

BTW, Leslie: Which patch did you use? I attached a second patch as
Andreas forgot to include the changes in hw/pc.h.
Cheers & Good morning to the europeans ;)
