The most recently available Macs that are 32-bit only, the Core-series Mac Mini, were shipping a hair over 4 years ago.

The first generation of Intel-based desktops used the 32-bit-only Core processors. The last model to switch to the 64-bit capable Core 2 processors was the Mac Mini; the announcement of the new models was made on August 7, 2007.

I don't know if this information will affect decisions (I personally prefer 64-bit by default) but I thought it best pipe up, just in case.

I'm game either way. I've heard no serious issues with the 64-bit version,
so we could "default" to it, or only build it. At this point, only 5+ year
old machines or folks still on 10.5 would be out.

I have such a machine (and it still works fine).  I'm pretty sure,
though, that I had to manually compile GHC for the last two releases.
Either due to some installer issue (10.6 required) or because of a
missing bindist which would allow me to put it into a custom
directory.  So, as long as this path is still available I don't mind
dropping a the 32bit platform installer.
