Assuming you are using SNAP Graphics, that would be one large desktop.

No.  As I understand it, that just lets you have a text-only console in addition to 
the regular screen.

None that I am aware of.

1x/2x are slotted differently from 4x/8x.  Some motherboards have an AGP slot 
without any separators, which (in theory, at least) means that any AGP card can be 
used.  The majority of recent motherboards with an AGP slot (the newest ones 
have PCI Express instead) are slotted for 4x/8x only.  Some cards are slotted such 
that they will fit in any AGP slot, but the newer/better ones are slotted for 4x/8x 
only.  To make things even more confusing, there are even some 2x cards that 
are incorrectly slotted to fit in any AGP slot, and will fry a 4x/8x motherboard 
because the chipset doesn't support the different voltage (a poor design choice, in 
my opinion).

Don't think so.
