Tested in 2.6.32-rc8 and 2.6.32 final on a G4 eMac.
Works fine, except for the yaboot problem:

> /sbin/installkernel 2.6.32 vmlinux System.map 
ofpath: Driver:  is not supported
ybin: Unable to find OpenFirmware path for boot=/dev/sda2
ybin: Please add ofboot=<path> where <path> is the OpenFirmware path to /dev/sda2 to /etc/yaboot.conf
ofpath: Driver:  is not supported
ybin: Unable to determine OpenFirmware path for macosx=/dev/sda4
ybin: Try specifying the real OpenFirmware path for macosx=/dev/sda4 in /etc/yaboot.conf

(userspace is YDL 6.2)
