mol problem. macosx partition locked. any suggestions?

[Roger Scow]

Sorry for the cross post.  I've asked before, but no joy on progress.

iBook 800.  MacOSX.3.5 partition on /dev/hda9.  YDL 3.0.1.  mol and
mol-kmods are up to date according to yum.  I've made appropriate
changes, I think to the molrc.osx config file, etc.  I've searched the
mol archives.

So, here's the deal:  When I type startmol -X, the full screen video
kicks in, the tux-loves-the-apple logo and the OSX spinning cogwheel
appear.  And that's it.  One hour later, no change.

When I get out of this (ctrl-f8) I can command-C and stop mol.  Or kill
<pid>.  The terminal shows no major kluges, but the mol.1.log shows
"/dev/hda9 this volume is locked".  

I've gone into OSX, repaired permissions, etc.  The only HFS+ partition
that has an operating system is hda9.  The other partitions are system
partitions, etc., but no OS there.  

How do I unlock the damn partition?  Mount shows no inappropriately
mounted volumes.  umount /dev/hda9 says that that volume isn't mounted.

Short of a YDL reinstall (which seems like a stupid thing to do), what
should I try next?

Best,

Roger
