Morning ...
I'm having a bugger of a time getting anywhere with the KTR stuff,
for, as soon as I enable it, the system slows down so badly that I can't
get into X to hang it ...
Figure that I'd try killing off *everything* not required (named,
ethernet interfaces, etc), so that there was less happening, I started up
X ... wouldn't hang.
Rebooted the machine, so that everything was running 'as per
normal', and started X ... dead in no time.
Looking at the IRQs that my machine is running with, according to
dmesg, I notice a few 'overlaps', and wonder if that could be the cause?

My sound card overlaps with fxp0, and fxp1 overlaps with the
HighPoint controller ...
Grasping at straws here ...
