Voila to you guys' reply!
See, Milestone guys (doshaska, nadlabak) made it run on ICS so I think it's possible to build the driver from that source (Linux n00b again, no idea how to). Question is, never had anyone tried (or thought about this) before?
Plus the latter question, any easy way to cross-compile NIT and CM sources? At least if rev.121 driver fails we can always have a working CM7.2 RC1 from @vakkov (cheers)...
