Devil's advocate here (literally), but:

Nokia casing with NOKIA logo - can be filed down, but the next one,

Using N900 (Nokia patented design) while promising to deliver a full device - can be avoided by only shipping boards and private channel information on casing shipping/montage, but this will kill a lot of the appeal.

Marketing using Fremantle (tm) as part of product information (pulling as hard as I can from my ***, but they can better) - easy, just move to the Freemantle untrademarked term to what this will be flashable with.


I did suggest a separate thread for legal discussion, might be worthwhile to move this there and ask any legalese speaking friends if they see any problems (or can come up with some, just in case). There could be further problems if booting even debian will need Nokia's driver blobs or similar
