How does this affect dual core CPU's though?  I was told that one
needs -686 to actually use dual cores at the same time.  Please
advise.

And my experience seems to bear that out.  I installed dapper on a
dual core machine about two months ago.  After install, cat
/proc/cpuinfo showed only one CPU, but then I did
sudo apt-get install linux-686-smp  and after that cat /proc/cpuinfo
showed two CPUs.
