Well, first, developement on PPC kernels is done on hq.fsmlabs.com
bitkeeper trees. Linus doesn't always have the latest fixes. We do send
patches quite regulary, but they are not always merged immediately by Linus.

Look at www.penguinppc.org for more infos about those trees.

Paul sent Linus a set of patches against test10 final, they have not been
merged by Linus yet.

PCI have been long fixed in the bitkeeper tree.

Works nicely with HID kbd on the bitkeeper tree.

For 2.2, I strongly suggest you use either the bitkeeper tree on
hq.fsmlabs.com, or Paul Mackerras rsync tree. I beleive Paul will send
updates to Alan soon, we have a huge diff against the official 2.2.x tree
for now.

>- all: G4 internal modem doesn't work. Suggestions ? I absolutely need it !!

That's something I've not checked. Paul fixed some internal modem issues
in macserial.c recently, I beleive those fixes are in the bk and rsync trees.

You need the latest gmac driver which is, again, in the trees mentioned above.
