I have not attempted 9.10 as yet. So I have no help to offer.

I have two AF12's running fine under 9.04 (32bit) with
2.6.29.1-rt8-custom kernel (the so called Luke kernel). I was never able
to get it to run with no xruns with UBStudio with the 32 or 64 bit
UBStudio 9.04 "out of the box".

In fact, if I remember correctly, I installed 9.04 from Conanical, and
added the UBStudio package, and added the rt custom kernel.

I thought UBStudio install handled the "re-config" to the old firewire
stack, but you might verify that that indeed has been done. Others here
probably know the commands to do that off the top of their heads.
