Yes, I can confirm this.  The only difference is that I have to boot
with a lower resolution (1024x768), otherwise my monitor stays blank
(even though it is capable of displaying higher resolutions).  I can now
switch VTs as well... this has never been possible for me before (after
X had started, all VTs always weren't capable of being displayed
anymore).

So thank you Roger, for this hint!  My Mac Mini has more functionality
now ;-)

Cheers,
Bram
