I have 500MHz UltraSPARC II on my desktop running Gentoo Linux. :-)

I've got ghc 6.8.2 working, but only -fvia-C and only unregisterised.

"-fwrapv" is an option to some version of gcc, but I couldn't tell you

Me too :-), or in my case use it a bit quicker. Unregisterised ghc
builds are pretty slow.

Our tentative plan is to partition our T2 server using logical domains
and run both Solaris and Linux. We'd like to set up ghc build bots on
both OSs.

I guess this is something that anyone with an account on the box could
do. So once we get to the stage where we're handing out accounts then
hopefully this would follow.

The project isn't aiming to get the registerised C backend working
nicely, we're aiming to get a decent native backend. That should also be
much less fragile by not depending on the version of gcc so closely.

That's a tad harder. Needs lot of build system hacking.
