Now this is pretty basic, but I have Googled around a bit and can't find
the answer:
What do I look for (in /proc/sys/kernel I assume) to tell me whether a
2.6 kernel has realtime preemption compiled in?

Hi Mick,
If you enabled it you can copy /proc/config.gz somewhere, gunzip it
and grep for PREEMPT
Cheers,
Mark

If you're running some version of Red Hat you can look in /boot for
config-whatever files and just grep -i for preempt in the one that
corresponds to the kernel you're running. I don't know if this is the
same on other distros.

Yes it is. Moreover `uname -a' tells you if preempt is enabled:
$ uname -a
Linux spma33 2.6.15.2-vanilla-2 #1 PREEMPT Tue Jan 31 16:49:26 CET
2006 i686 GNU/Linux

OK, thats simple enough. I'm on Fedora at the moment and didn't find
config.gz in /proc, but there is a config file in /boot.
So on a running system, there wouldn't be a file of any kind in
/proc/sys/kernel, like /proc/sys/kernel/rt_preempt for argument's sake,
with a value of 1 ?

That's the hard way, the easy way is:
zgrep PREEMPT /proc/config.gz

/proc/sys/kernel/version on my system (Slackware-10.2, with a custom
2.6.15 kernel) contains the following, which might be helpful:

realtime preemption kernels carry the suffix "-rt" in their name. So
simply check the
uname -a
output (Of course unless the builder removed it. But why should he?)
Have fun,
