I have a DViCO FusionHDTV7 Dual Express that I would like to recommend for support.  I believe it meets the criteria, though feel free to strike me down if that is not the case.

It is on my to-do list to add support for this card, but it is behind a few other items on the list.

I have started a wiki for the card here http://wiki.linuxmce.org/index.php/DViCO_FusionHDTV7_Dual_Express

I have a bunch of Intermatic HA20C dimmers that are rated for 600w.  I currently do not have any installed that bump up against that limit, though.

Yes, I've been reading up on the developer's guide and it does seem very straightforward.  I've just got to get my feet wet with creating a GSD.

I'm soaking up as much from the wiki as I can and I'll try to get started later tonight, perhaps.

I just got my IT-100 in the mail.  Is anyone still working on this, or am I starting from scratch?

These cases are not bad...http://www.mini-itx.com/store/?c=54#m350

They have a nice bundle over there at mini-itx with the dual-core, 2GB DDR2 and m350 case for ~ $325US...not too shabby.
