SMP is implemented in 2.0.x kernels. Some kernels are better at it than
others, and sometimes you have to edit the kernel Makefile to get SMP
support (this is all explained in the SMP HOWTO).
The trouble with SMB in 2.0.x is not that it is unstable, but that it
isn't very efficient. If your processes are CPU-intensive, and/or you
have only 2 CPU's, you will be fine, but for processes that do lots of
system calls or I/O they tend to spend a lot of time waiting for kernel
locks. But this is not disastrous, just suboptimal. It is much better in
2.2.
