Model: PowerBook Duo 280c

PMU v2 ADB: Known to work on PB 190 but misbehave on PB 5x0 and Duo 280.

NCR5380 SCSI: Broken.

Serial: Broken. Cannot be used from userspace, but can be used for kernel debugging.

NuBus: If initialized by MacOS, some cards can cause an early kernel panic on some models. Workaround: boot MacOS with extensions off, or use Emile instead of Penguin.
