There's a bug in how FreeBSD Update handles /boot/kernel. Basically, it's
supposed to figure out if you're running a GENERIC or SMP kernel, and get
the appropriate updates based on that; but I incorrectly assumed that the
SMP kernel would identify itself as "SMP". Instead, the i386 SMP kernel
identifies itself as "SMP-GENERIC", while the amd64 SMP kernel identifies
itself as "GENERIC", with the result that

(a) On FreeBSD 6.2 i386 systems running an SMP kernel from /boot/kernel,
the kernel will not be updated, and
(b) On FreeBSD 6.2 amd64 systems running an SMP kernel from /boot/kernel,
the kernel will be replaced with a GENERIC (non-SMP) kernel.

I'm working on a patch for this and will be talking to re@ about having an
Errata Notice sent out about this.
