Run lspci -h and look under "Selection of devices" - it should work.
But the sh fu may be broken by now.

Thanks. I updated the EHCI page with the SB700.

It's interesting that you have two EHCI devices with a debug port
each. I don't know what coreboot does in this case. Not much to do
since you can't test, but you could look around at the port registers
to see if you can locate if the debug port(s!) actually go(es)
anywhere on the board.
