Ah, the joys of running a UNIX that doesn't have an fsck capable of
actually repairing its own filesystems...

Maybe. Dunno if OS 9.x would read it, but it could work.

You can 'apt-get install hfsplus', then use hpmount to "mount" the
device, and hpcp to copy critical files off the filesystem. I'm not sure
if hfsplus yet supports HFS+ writing, but for your purpose that doesn't
sound like a high priority - it'll work well enough to at least get
files _off_ it.

It won't overwrite the bootstrap partition, but it will change what's
set in the NVRAM as the boot device. You can either hold Option at boot
(if your system has an OF with the Option menu feature - 4.x only?), or
boot to the OF prompt and type:
boot hd:[bootstrap partition number],\\yaboot
at the prompt, and Linux should boot normally.
