Well, PPC gives EDID data through OF, but this has its problems too --
primarily that you only get a resolution and a number of colors, not a
real modeline.

We've got various KVMs of differing quality around the office in
Westford, and they don't usually seem to block it -- but they don't
cache it or probe it either, and if you're not connected to that box at
the right ill-defined moment of the BIOS POST, well, you're not
connected to it.

It makes it less likely, at least.

No comment on the rest; I'm sure you know the details better than I
do ;)
