NetBSD 1.6I-MP only sees one cpu

(sorry for the crosspost, I'm not sure which of the two groups
should get this message.)

I have a system running 1.6I from current-allsrc sup'd down a
day ago. The system comes up just fine now, with one exception.
It only sees one of the two CPU's.  The system is a Compaq Proliant
PPro200x2.  When it comes up I see:

  NetBSD 1.6I (belldandy) #3: Mon Oct  7 17:38:41 PDT 2002

The kernel reports this is a uniprocessor system, even though it
isn't. Is this a known issue with this system or is there something
I can do to get the other processor to spin up?

Thanks!
