Ok, I'm not sure what happened to him exactly, it may well
be a video problem in which case your suggestion of using
ofonly video is correct.

I'll get one rsn. Note that in order to make that better, I've
just added to my tree a proc entry for ide-pmac. It appears
under /proc/ide/pmac, and shows, for each interface driven by
this driver, the full OF path (among others). I still need to
do something for PCI based controllers (like Promise) though.

An example of output on my tipb:

ide0 (KeyLargo ATA-4)
  of_path  : /pci at f2000000/mac-io at 17/ata-4 at 1f000
  bus-id   : 2
  cable    : 80 connector
ide1 (KeyLargo ATA-3)
  of_path  : /pci at f2000000/mac-io at 17/ata-3 at 20000
  bus-id   : 0
  cable    : 40 connector
ide2 (KeyLargo ATA-3)
  of_path  : /pci at f2000000/mac-io at 17/ata-3 at 21000
  bus-id   : 1
  cable    : 40 connector

(the algorithm to go from hdX to ideY is basically
(X - 'a') / 2, then remainder beeing the OF unit number
(0 for master, 1 for slave).
