I've downloaded the 10.5.6 update on my PowerBook G4, 12", 1.33GHz. After reboot, I get a kernel panic, saying "Unable to find driver for this platform: PowerBook6.4.../Kernel/IOPlatformExpert.cpp:1407"
Any idea what's wrong here? I already reset the PRAM and NVRAM. I'm on travel, so I don't have any boot disks and external HD available.
