I vaguely remember something about this.  I would probably be a good
thing to reference in the FAQ.

Here are some links:

This claims there is no -12 on early qube2's.

This makes it sound like there is no 3.3 volt lines.

The qube2 manual,
http://www.sun.com/hardware/serverappliances/pdfs/discontinued/manual.qube2.pdf
, only says that the PCI card can be no longer than 5.5 inches.  No
mention is made about available supply voltages.
