NexusHD2-Froyo ( Froyo 2.2.2) might be an option, but not ideal, its not CM based.
For those who would like to move to GingerBread:
HyperDroidGBX or HyperDroid CM7 are a good choice.
Be aware OpenGL 3D graphics in particular, will be a bit slower on GingerBread!

Piotrv seems to me that Opengl in Gingerbread is smoother if anything, can't seem to detect any slowdowns,
