How can I detect an SMP system in user space even when running an UP
kernel? Things like `cat /proc/cpuinfo' don't count.

How about simply running 'top' or a 'dmesg | grep CPU'?

As I already said, I'm running a UP kernel, thus top only ever sees one
CPU. The latter fails if the boot messages have already been cleared from
the kernel log.

This is just another instance of the `cat /proc/cpuinfo' class.
