Model: Quadra 630

CUDA ADB: OK.

NCR53c9x SCSI: OK. Occasional probe trouble on some models (?). Complains at poweroff.

Quadra IDE: OK.

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

SONIC ethernet: OK.

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.

Miscellaneous issues:

The real time clock is broken. Workaround: use NTP to set the time at boot, and disable filesystems' time-stamp-triggered fsck with tune2fs -i 0 /dev/whatever.
