You should feel priviliged. It took me months on and off to think I
might be close.
I do have some bad news though - you probably should have stayed with
since Matt did think that there was some endian bugs, and I am pretty
Paul had at least a floppy disk working.

Which should be the right device - this Powerbook is IDE, right? No SCSI
attached? Then it should be on /dev/sda. But maybe /dev/sda1 if it is
HFS disk? What does fdisk show as the partitions?

This is showing up correctly in /proc/bus/usb/devices and
/proc/bus/usb/drivers, right? The drive shows up and the usb-storage
driver is associated with it?
Any more kernel debug messages?
