I certainly understand. I haven't had time to do anything other than
keep an eye on the mailing lists in months.

The problem is not really that it needs to be hot-pluggable (tho in
theory several powerbooks support true hotplug of floppy drives), but
that udev relies on hotplug. Without the hotplug support, the device
nodes don't always get created correctly. You'll get it nearly for
free with a conversion to use the macio bus.

As of 2.6.13 (the latest I have on disk), the list seems to be this:
drivers/i2c/busses/i2c-keywest.c
drivers/ide/ppc/pmac.c
drivers/macintosh/mediabay.c
drivers/net/bmac.c
drivers/net/mace.c
drivers/net/wireless/airport.c
drivers/scsi/mac53c94.c
drivers/scsi/mesh.c
drivers/serial/pmac_zilog.c
Just as a note, I searched for macio_register_driver to build this list.
