2.4 used the device-tree exclusively for probing IDE on pmac, while 2.6
uses PCI probing when it's a PCI device. The device-tree method tend to
work even when we don't have the PCI ID, but it's dangerous: the driver
doesn't know the details of the timings for this chip revision etc...
and thus may well do crap. I wouldn't try too much with 2.4.
Can you try this patch ? If you don't have a way to build a patched
kernel, you may find somebody on linuxppc-dev list who can do it for
you.
