There are a gazillion of these. (Most of these are dual, there are a few quad cores mixed in. For XBMC, the dual core is more than powerful enough. The quad core won't fix software rendering, it's up the OEMs to get CedarX working (it's close) or Pivos to push out more amlplayer updates for utilizing the Mali GPU for accelerated playback.) http://www.alibaba.com/trade/search?fsb=y&IndexArea=prod...

It's like the AMLogic-M3 f16ref. There are a dozen different flavors of these and the roms are interchangeable but there's no community around them to get continuous integration and good builds of XBMC setup. There should be an effort to get a distro that will generate nightly builds to target these devices with Linux/Android and optionally XBMC.

I keep rehashing this and everytime I do I say I should start a blog or set of resources for this... I need to follow through but my other projects are more immediately exciting :S
