It may be that there's no way to break that 1-hour barrier. Maybe I
can convince Colin that, until full cross-compiling is available, we
sparc64 folks would settle for slightly-delayed binary security
updates (instead of never getting them at all). It's the very fact
that we're running on slower hardware that makes freebsd-update so
I'd still like to see what a quad Ultra 80 can do, though. :) Who has
access to one of these?
Chris, did you do any of the other things that the handbook
'Rebuilding "world"' section suggests -- noatime /usr/src, async
/usr/obj, etc? Also, are you tracking 6.2-STABLE, -RELEASE, or
something else? If -STABLE, as of when? Over time, these data points
may be relevant.

This'll do until we come up with something better:
FreeBSD - The SPARC to Serve
