[PATCH] Add cmd64x IDE driver to default pmac32 config

[lawrence rust]

The Blue/White Apple PowerMac G3 and early G4's use a cmd64x compatible
IDE disk controller.  E.g. lspci shows...

01:01.0 IDE interface: Silicon Image, Inc. PCI0646 (rev 07)

Unfortunately the default pmac32 configuration does not include this
driver and so PowerMac G3's can't load a root filesystem.  This is an
issue on a least Ubuntu since version 9.04, which uses the default
config as a starting point.
