Well, the i386 package won't work, but (assuming there's no arm package), you're going to have to compile it from that source package; unfortunately, it's not quite as easy on the N800 as on a typical PC, because you either need to setup a cross-compiler on the PC or install a native build environment on the tablet. The former is easy enough, but more complex to use. The latter is not easy at all, but when you get it, you can do just like on any other machine.
