opteron 175: only one core recognized

[Tom Vier <tmv@comcast.net>]

I tried to search the archives, but i got an "internal server error" from
lists.debian.org.

Looks like there's no seperate smp kernel anymore. 2.6.18-4 seems to support
smp, but it doesn't recognize my dual core 175. I don't see any newer
kernels.
