I have had the chance to see it myself, including some testing. The Mac Mini was the 2,3 GHz i5. To cut it short: The system was slow, flickering monitor, the cursor (and the entire system) was freezing occasionally, and only HDMI was working.
The Mini was booted from an external USB drive. The system was installed on a MBP 2011/Thunderbolt, from the original installer. The same problems occured as SL was installed on a MBP 2007 - from a retail DVD to the USB drive, and updated to 10.6.8. System profiler has recognized all hardware in both cases.
I have also checked some Hackintosh sites for tips. But it seems that it is easier getting a Hackintosh to work with Snow Leopard, than a 2011 Mac Mini!
