The are _all_ x86_64 (athlon X2 4400 based - 40 of them). But they are
all running 32 bit installs for now - convenience and (my) time
administration trumps absolute speed for now, hmm, myself I think the
speed change would not be measurable in the exponential realm of human
perception (5%?), _all other factors being equal_[*]. 

In the last few days I've started building and testing realtime kernels
for fc6 and I'm doing that with 64 bit builds as well. But don't hold
your breath for a full Planet CCRMA on 64 bits just yet, it is just
kernels for now :-)

[*] exact same hardware, exact same distro, exact same install, same
build environment, only difference being build on 32 bit version vs.
build on 64 bit version.
