OK. That's a pleasant answer. :-)

I added this:

::::::::::::::
/etc/security/limits.d/93-audio_limits.conf
::::::::::::::
# Increase priority of audio applications
# maximum realtime priority
@audio - rtprio 90
# maximum locked-in-memory address space (KB)
@audio - memlock 2000000

Fedora's jack-audio-connection-kit-1.9.8-9.fc17.x86_64 package added this:

::::::::::::::
/etc/security/limits.d/95-jack.conf
::::::::::::::
# Default limits for users of jack-audio-connection-kit

@jackuser - rtprio 70
@jackuser - memlock 4194304

@pulse-rt - rtprio 20
@pulse-rt - nice -20

By permissions, are you meaning

crw-rw---- 1 root audio 10, 228 Oct 10 22:47 /dev/hpet
crw-rw---- 1 root audio 254, 0 Oct 10 22:47 /dev/rtc0

[kevinc #28] groups
kevinc root adm disk wheel cdrom man floppy games audio users jackuser

I'm having IRQ crowding issues, and I was headed at trying to
get rtirq going in order to help this. I believe rtirq *does*
require an RT kernel.
