I've posted a patch in my mail titled "Intel refactoring and microcode 
updates" that adds support for socket 775 CPUs, along with their 
respective microcode updates. Unfortunately, the updates are too large 
to fit in flash, and with v3's compression support, I've been tempted to 
just give up and hold off until v3 works (there is also a generic intel 
option, which supports any intel cpu, but lacks microcode updates, those 
can be done through the kernel later). I've also been messing around a 
little with an i945 board, but I won't get seriously working on it until 
I've wrapped up everything else I've got going.

There are also some embedded boards, PC Engines alix1c for instance, 
that are still for sale. There's also the Gigabyte 2671gxdx, which 
should be available soon, and a handful of Asus and MSI boards, just 
look for the ones with the nvidia mcp55 or via k8t890. I'm working on 
support for jetway's j7f2 series right now (via c7/cn700), it's just 
about finished and there should be a fresh patch the next few days.

v3 isn't ready for production yet. It's coming along well, and the first 
working target will probably be the aforementioned alix1c.

Not at this time. Undocumented embedded controllers tend to get in the way.
