This is yaboot not working properly most likely.

What is /dev/hda8 (ie. what partition is this?  /boot?  the apple 
bootstrap?)

No, OS X will not show the Linux partitions.  Unfortunately.  =)

Good move... =)

My mind is fuzzy, so I'm probably not too much help, but if you can 
provide the details of /dev/hda8 that'd be great.

The other option might be to boot off the 8.2 install CD into rescue 
mode, then chroot your root partition (usually automatically mounted in 
/mnt, so do "chroot /mnt") and check your /etc/yaboot.conf file to make 
sure it looks ok.  Also try running "ybin -v" to regenerate the 
bootstrap stuff.

The other option, that I've encountered on my newer G4 imac, is I've 
had to power down the imac after getting it stalling like you describe, 
but on the next power up yaboot always comes up fine.  So for me it's 
just a nuisance.
