Bind not recognising multiple CPU's

In my haste, I've neglected a few details I didn't really think where
important as I was asking a generic question, however after prompting from a
list member (thank you) I agree that it is important.

I am using a home developed Linux distribution, built from the 2.6.9-1
headers using the 2.6.9 smp kernel. Built with bin-utils

The platform is a dual Pentium3 system. 

Bind version 9.3 built from gcc 3.4.3

Hope that adds a little more detail.

Subject: Bind not recognising multiple CPU's

Hi all,
I've decided to move one of my named servers to a more powerful and
resilient server.

I've also moved from 9.2 to 9.3 in the server move, which is fine as config
style the seem pretty much identical.

The new machine I'm moving to is a dual CPU machine.

When I start bind I see in the syslog 

Dec 20 11:57:15 alesi named[18438]: starting BIND 9.3.0 -t /chroot/named -u
Dec 20 11:57:15 alesi named[18438]: found 1 CPU, using 1 worker thread

I thought I'd try to force the issue with 

Dec 20 11:57:36 alesi named[18458]: starting BIND 9.3.0 -n 2 -t
/chroot/named -u named
Dec 20 11:57:36 alesi named[18458]: found 1 CPU, using 2 worker threads

Which it starts the 2 workers, but it still also only see the one cpu.

1.)	How do I make the machine recognize the dual cpu, and split the
functionality over the paid of them ?
2.)	I've dug around and found no problems with running bind over
multiple CPU's but from experience has anyone had any problems with this ?
