GPS data would also be nice to save to log files.

FWIW, Kim's GPS project currently does this. It uses a rw mounted partition for swap, log files, configuration, etc.

It seems like many people are asking for a place on the empeg they can write to for various reasons and we have that spare 32? meg partition. Why don't we just use it? fsck times for a partition that small are trivial so even if it gets fsck'd every time it isn't that big a deal as long as apps are prepared to occasionally loose data written to it. Of course if we could ext3 it that would be even better.
