AFAIK you can set up a motherbord to supply the 5VSB on
a USB header. This is used so that keyboards can wake
up the PC.
Woudln't it be possible to use this same mechanism as a
'power on' kind of thing? (Maybe as a 'from standby?')
If it isn't possible because you'd have to
emulate/provide a keybord driver/device ID/thing, then
mabye add 2 pins to be used to connect to the power
button directly (in parallel with the real power
switch) so that it'll send a 'switch' signal.
This would require (beside the 5VSB hook up) that you
store one IR code in the IC that, when triggerd (in
offline mode?) flips the switch pinout.
If it's an I/O pin, you could even use the pin to
detect wether the switch is being pushed (while D/Ced
from the motherboard) in 'online' mode to set the IR
code to be used.
