Someone mentioned that the ppc headers were missing some definitions that
are in i386.  I'm referring to copying those changes instead of changing the
includes... I just wanted to mention it, in case it affects something I
don't know about.

asm/ide.h is included from linux/ide.h, and IIRC gcc doesn't care how far
away the code is included... as long as it gets what it needs.  Probably
just including everything before parsing...

Oops, brain fart.  Did any of those APUS have PCI?  If not, then the change
may not be needed.

Michel, your pci-fixup patch is incompatible with Donald Becker's rtl8139.c
(from his site) driver with the new pci-scan.c module from his web site.  I
thought I'd let you know. 

When I insert the module, I get an oops.  On these machines (PPC mac 7200,
6500, & oldworld g3) I have had to use his new drivers to get reliable
ethernet access.  The ones in Linus' kernel haven't been reliable for me.

Is there any chance that your pci patch would fix any problems I've been
having with the eth drivers in the kernel.org kernel?

What behavior could I expect from the system if I used the ide patch without
the PCI-fixup patch on a promise udma66 card?
