Got the following from Alsoft about Diskwarrior 3.0 and Panther:
DiskWarrior v3.0 will rebuild the directory of a disk running Mac OS X
10.3 when started under Mac OS X 10.2.x. The best way to achieve this is
to start the computer from the DiskWarrior CD or another media source
running Mac OS X 10.2.x and run DiskWarrior from there.
DiskWarrior v3.0 will not rebuild the directory of a disk when started
under Mac OS X 10.3.
We hope to release a new version of DiskWarrior in mid November. This
new version of DiskWarrior will run under Mac OS X 10.2.x and later,
including 10.3.
Also, DiskWarrior v3.0 will not disable journaling.
If you have any additional questions please feel free to contact us.

Be advised though that some persons have reported that DiskWarrior trashed their Panther drive when booting off the DiskWarrior CD. Others have said they have had no problems.
