It does have Kmplayer ported to it (check FMC.) I guess it works too as I installed mplayer and that and now my Orb feeds work so I can still watch live TV on the go.
Like said, pretty much everything else on your list is there (and I think the mail client is worlds better than the N900s Modest) and the only thing that isn't is faircrack/cleven but that's being held up by needing to get around Aegis for it to work. AFAIK, devs are getting around Aegis with open mode but I'm not sure a new kernel has been developed yet for cleven, etc.
