Don't quote me ...since I cannot exactly recall...
But I think this question was already roughly answered with a "it should work on the n8x0s"
May want to get clarification on that though...

I don't see why it couldn't if the black box blobs of doom are dealt with...
and since a great deal of work was backported from the n900 to the n8x0s... back in the day...
it should be that much easier to deal with.

and...mmm...ram shouldn't have much to do with it..
if I can run antix linux on an old pc...and I mean old...
(antix can run on a p3 with 256mb of ram...soooo...)
there is no reason why we couldn't run leste on the n8x0s...
(sure the real heavy stuff may be too much ...but modest and light apps should run....which are the majority ..since tons of linux progs that were designed to be compact and run light anyway...soooo...moot point there...)
