I've got a 770X with debian on it, and I've been playing with
hotswapping in my ultrabay also- I hadn't got anywhere for ages, then I
noticed a solution (almost) under my nose.

hdparm (for those not in the know, a utility to fine-tune things like
DMA transfers for your harddrive, with a debian package), comes with a
script called 'ultrabayd'.  Using a combination of hdparm & tpctl, this
does roughly what you've been trying to do with enabling and disabling the
IDE bus / FDD bus automagically- all you do is leave it running.  This
has given me by far the most success- I can take out my DVD drive,
interchanging it with a FDD fine.  The BIOS only
lets me interchange it with another HDD when I'm in ACPI mode, however
when I do, it recognises it, and fires it up, getting the model and
anything-- then the kernel panics.  I haven't had time to play with it
any further.

In short, give this script a go- It'll be interesting what happens on
your laptop (sync those drives first).......
