Remote serial consoles allow access to the systems during boot, but might not be supported by the BIOS. I think this is worth looking into, since the APC power switches aren't much use in diagnosing a machine that hangs during boot.
We've discussed this several times before... most, if not all, of the servers in the farm are capable of BIOS redirection.. the BIOS is displayed on screen and to a serial port at the same time. GRUB supports serial terminals on it's own.
(I use these things everyday on my own machines.)
