Default DS port

Yes, the Nintendo DS. Yes, yes, I know: http://www.mersenneforum.org/showthread.php?t=10275
I'm just curious if anybody has a guess as to just how slow it'd be for prime-searching/prime-eliminating-by-factoring/full-factoring. It'd also have to fit in very few MB of RAM. (http://en.wikipedia.org/wiki/Nintendo_DS_Lite says 4 MB, which sounds about right) You don't have to worry about background tasks taking up any of the 4 MB though. It's limited to one app at a time. I'm sure it'd suck the battery dry faster than you could say "this really isn't a good idea," but hey isn't that what AC adapters are for?
There's even a WiFi connection to get assignments from PrimeNet if you want.
There are expansion cards that go in the GBA slot (so that would be only for the original DS or DS Lite, DSi already has more RAM I believe) to allow for more RAM.
(I was inspired by flouran's "iPhone App" thread)

It would be kinda cool to have my DS running the software, but it would be very very slow. It's not the ram im worried about, its the processor. According to this website: http://www0.dealtime.com/xPF-Nintend...d-World-Bundle (it shows the specs in the page) The Arm 9 processor is only 67 mHz. I don't think it would be worth the time or effort to write software for the DS.

Absolute best case: 100 times slower. More likely: 1000 times slower with optimizations, 3000 times slower naively.
