I have it 'working' the graphics are screwy but it is passable. I used Super Duper! to clone an older mac mini and then restore it to the lion partition. It worked fine in the office until I started to use the HDMI port and 16:9 resolution. When using the HDMI two monitors show up and the cursor is on the 'other' screen (ie the one not being displayed). If you set the two displays to 'mirror' things work pretty well - finger's crossed!
