I installed FC6T3 under Parallells on a MacBook. It automatically chose the
display size of 1600x1200 when the MacBook monitor is only 1280x1024.
FC5 required configuring the display size. In combination with bug #206900
where s-c-d won't change the display size, I had to manually edit xorg.conf to
get the right size.
I am not sure if Parallels supports EDID and correctly reports the resolution to
the guest OS. I put in a support ticket to find that out.

There does not appear to be any DDC information available, and the faked VBIOS
is reporting a maximum resolution of 1600x1200, so that's what we end up using.
As it stands, this isn't a bug we can fix.
If Parallels gains the ability to report native screen size somehow this will
get fixed. The options are:
- set the maximum resolution available through VBIOS to native screen size
- add DDC emulation to Parallels (and wire up our vesa driver to use it better)
- add VBE Panel extensions support to their VBIOS (and wire up our vesa driver
to use that info at all)
