(BTW, my current laptop is a T510 and runs a Multiface with the same 
adapter fine with 3.2.x rt, but on fc14 i386 for now)

Hmmmm, I think not. I can try to remember to bring an rme pcmcia card 
tomorrow from home and test on my test laptop (with a Multiface II).

For the hdspmixer problem I used to have a patched alsa-tools package in 
Planet CCRMA, 1.0.24 was not good enough for the latest versions of the 
hdsp driver. I would have assumed that 1.0.25 fixed those problems - the 
patch came from alsa - but it seems it did not, which is weird.

It is strange that jack itself is not happy with newer kernels. That 
would seem to suggest a kernel bug with your particular hardware.

What do you mean by "jack locks up very quickly"? Do you mean the whole 
machine locks up? Or just the jackd process? Does jackd print anything 
before it locks up?
