Embedded Linux howto?  Device drivers and bit-banging on RS-232/485?

I'm kinda thinking only of what I'd like to learn myself as well as burdening Alan with that suggestion, so I'm hoping there are other presenters as well as good interest.  

I have a single-board ARM with dev toolkit that has been sitting on a shelf forever...  It's got USB, ethernet, and RS485 ports.  At least I could bring that to the table, if that's at all practical.  If I know by today's end that this could be used I'll at least see if I can boot and minicom into it tonight.

If anyone has a simple device that can be wired to a 5V signal or COM port or USB, that could give us some direction.
