No need to apologize - it's a good question, which I've been wondering about myself. If memory serves me, some 770 users have partitioned their MMC cards using Linux tools, yielding (for example) a dedicated swap partition and multiple ext2/ext3 partitions. There is a compatibility downside, since Windows won't mount those filesystems (as USB mass storage) without third party help. But I believe solutions are available.

I don't know whether the same can be accomplished with FAT32, but it would be worth finding out. One option I considered would be partitioning a 4GB card with street maps on one volume and topo maps on the other. You could then toggle freely between them in Maemo Mapper, much as you can in Google Maps (minus the hybrid overlay).

If nobody else chimes in with a definitive answer, I'll try some experiments.
