Well, enabling HRT allowed it to boot, but there are several casualties.

For some reason, "heyu turn a14 off" which works with non-rt kernels, seems
to hang forever, or until its ctl-c'd. And all my control scripts that
use heyu fail. I killed the background processes that my startup script
starts, re-ran them by hand and now its working. Shakes head in
puzzlement...

Tvtime is still dead, sits in a blue screen & no sound. I have a cx88
tvaudio process running at -5 nice that I can't kill, if I do its back on
the next htop refresh.

/usr/local/bin/upsd (the belkin supplied version) is using up to half the
cpu. The cpu of course is running 10F warmer. And a SIGHUP from htop
killed it. And restarting it via an "sh ./S99bulldog" causes a repeat of
its cpu hogging.

Audacity-1.2.4 takes 30 seconds to clear the busy icon when started with no
arguments from the icon. I don't recall observing that before, but its
been a while since I ran it for any reason too, so my memory could be hazy
on that.

Hot-babe, (a debian toy) when running, looks normal, but uses 20% of the
cpu, which contributes to the strip job. :)

All in all, it could be worse. Now I have to shut down and replace the
ailing battery in my ups, it just walked in the door. And that has
nothing to do with this kernel 2.6.18-rt2.
