The PCI device table in the powermac IDE driver isn't properly
terminated.  Depending on how your kernel is linked and other random
factors, you can end up with this driver matched against any other PCI
device in your system, possibly crashing at boot.

Thanks to Heikki for tracking this down with me, the bug have been there
for some time, though it rarely hurts due to luck.  In this case, the
switch from .22 to .23-rc9 is causing it to show up due to differences
in the resulting layout of .data I suppose.
