Installed a 2.6-test11 kernel on the powerbook:
rsync -avz --delete source.mvista.com::linuxppc-2.5-benh .
Had to use Ben's tree, since the old Radeon FB in the stock kernels breaks for me, whereas the new one which is only in the linuxppc tree breaks. Here is the config file I used.
So far everything seems to be working smoothly. It does appear to be a bit more responsive.
On another side note, I've packaged silky 0.4.1 (only the sparc build is missing ATM)
..I'm so afraid I did a mistake 40 minutes ago..
