OK, the new kernel is running. I can at least report that I don't get
a total freeze and I do get sound.

Do I need to set IRQ priorities like I did earlier with Ingo's
patches? I.e. - decide which were threaded and on-threaded? Other
things? IRQ11 is fairly high priority, but it is gettign beat out by a
few things. I'd probably like sound and then 1394 to be the highest
after system functions like RTC.
