Erlang & Hyperthreading

There's some sort of company being set up in Dunedin to do something or
other with multicore/hyperthread-style processors.  I'm sorry to be
vague about this, but I'm not actually involved.  However, the University
_is_ involved, and a colleague in this Department _is_ involved, and it
seems that through him I will have access to an UltraSPARC-T1 later this
year.  (I hope I've got the name right:  8 UltraSPARC cores on the chip,
4 virtual processors per core, running Solaris 10.)

I spoke briefly to my colleague about this today.  (Erlang?  Can that
do multithreading?)  He/they *would* be interested in running Erlang
benchmarks on that machine when the machine is ready for Erlang and
Erlang is ready for Erlang.  My colleague is generally interested in
parallel programming (distributed shared memory is his pet topic),
telecommunications (he teaches our TELE papers), and is open-minded about
non-mainstream languages (he has published papers on parallel Prolog).

So please note me as
 - pantingly keen to get my hands on even an alpha release of a
   multicore-ready Erlang
 - interested in suggestions about suitable benchmarks
