While Linux generally supports joining two partitions into a single
logical one, I think there's a huge practical problem with it on the
N800:  It only comes with two SD card slots, thus tying them together
seriously hinders your flexibility.

You won't be able to swap cards to e.g. listen to a different music
collection, unless you're willing to specifically prepare a pair of SD
cards for every use, and get that to work on your PC's card reader as
well, if you have one.
