I can empirically support Lee's statements. I run a plain
gentoo-sources 2.6.13 kernel on all of my 32-bit machines. I have no
problems even with Jack running at 64/2.

It's only on my AMD64 machine that I've had to use the -rt patches. I
suspect that when the last of the problems get worked out of the
64-bit kernels (or NIC drivers, or video drivers, etc.) I may not need
to use the -rt patches for that machine either.

As Lee says - try it. It just may work.
