Dell uses an OMAP 3430 in their Latitude notebooks (for instant on, long running access to basic features) which runs MonteVista Montebella Linux and has a mozilla based browser. If you look at ManteVista's development map they plan to have Flash for this device.

I think considering Dell's pull and all, it seems likely that they will actually have flash for this OS and device, and it seems to me this would probably work fine on N900 as well. What do you guys think?
