This new set of patches perform the rename (to be replaced with SVN
operation). CMD646 is used instead of pmac ide.

Debian 4.0 R6 cd image boots, installer starts but keyboard does not
work (probably because OpenBIOS doesn't advertise OpenPic).

The 6th patch is not wanted, it just switches CMD646 back to pmac, but
it's there if someone wants to play.

Should these be committed or do we want to wait for more OpenBIOS
updates? At least the OpenBIOS patch, patch #0 and patch #5 are
harmless.
