OK, copied from mac partition back to linux:

Yes, I installed in MOL.

First attempt was installed from original 10.2 Jaguar CD (booted in 
MOL), upgraded to 10.2.3 about a week ago, then to 10.2.4 a couple of 
days ago. Second and subsequent attempts were  installed from the 10.2.3 
CD shipped with the last ADC select mailing (again booted in MOL - 
flawlessly!) and then upgraded.

In all cases the install has been to a /dev/loop device attached to a 
5gig file. The file has a normal looking mac partition map (HFS is part 
9) which was formatted with the Disk Utility available at boot time on 
the install CD.

There is a "real" 30gig 10.2.4 partition on the disk that was installed 
while booted in OSX native. That partition boots OK from 
yaboot/openfirmware but exhibits the same hanging behaviour under MOL, 
whether I configure it as /dev/hda or /dev/hda13 explicitly.

I think so too. Tried the Debian woody 2.4 dist kernel as well as  
2.4.20-ben4 and 2.4.20-ben6. Also tried the mol package from sid, the bk 
source, and rebuilt everything (kernel, modules and mol) with gcc 2.9.5 
as well as debian-unstable default gcc-3.2.3. :)

I forgot to mention that the first time. It show nothing, just blanks 
the logo and displays a steady cursor in the top left corner. It does 
_not_ get as far as showing the "standard timeslicing quantum" that you 
would expect. I have not yet checked if Apple has released the 6.4 
darwin kernel to anon cvs yet.

OK. Meta-G set it running, but Meta-S had no effect (comparing with what 
I see with 10.2.3) the cpu continues to spin. I confess I'm new to MOL 
so forgive me if I have missed something obvious.
