This thread is about porting maemo fremantle to other hw platforms than N900. It's considered feasible, given a few hw prerequisites are met, which will be met on Neo900. So I don't see why this negativism in here since a few posts.

@wikiwide:
The kernel level driver will be CRTOUCH specific, the /dev/mouse device is API-compliant. So no problems with using the new dual-touch controller with any usual linux. Fremantle has no OOTB support for multitouch, so it's up to particular apps to use this feature.
FMRX also might be different to N900 on hw level, but API should be pretty similar and V4L2-compliant. The restrictions you mentioned are on a sw level and thus it's up to the implementation in fremantle-ported if they apply.
