On my system, the vanilla 2.6 with preemption is usable for audio, but
nowhere near as good at low latencies as a properly patched and tuned

Yes, I think it will.  But, 2.6 provides a mechanism for doing this as
a kernel module with no patches required.  Here is an experimental
module I built based on earlier work done by Torben Hohn...
