a simple one this time -- how can i tell if my currently-running
kernel is SMP capable? i'm guessing that, if i list /proc/cpuinfo and
more than 1 CPU shows up, that's a dead giveaway.
but what about on a truly single CPU system? i can still be running
an SM kernel, it just wouldn't be obvious. so how do i tell? thanks.

Are you running an upstream kernel, or a custom compiled kernel?
If you rolled your own from source, you can tell if you do a make
xconfig (or make menuconfig, if you're of the curses persuasion) in
/usr/src/linux (or where ever you untarred it). If it's a vendor
provided kernel, SMP compiled kernels almost always have a -smp- in the
name. Try 'uname -a' or 'uname -r' to see the kernel info. FWIW,
running an SMP kernel on a single core box is ok, but you'll not want to
run a kernel compiled for single core on a multicore platform. Intel
HyperThreading CPUs are considered SMP, IIRC. HTH.
