The word that's circulated the last couple of times this has come up is that
you should just go ahead and use VFAT unless you really need the Unixisms.
CF is designed with a FAT-related FS in mind.

If you do need the Unixims, the recommendation is to stick with ext2.
Apparently both ext3 and reiserfs require a fair chunk of space for their
journal, which negates any utility they'd have in minimizing flash wear.

JFFS2 won't work out-of-the-box with a CF card becase CF cards present
themselves as disk drives, not MTDs. Someone hinted at a way to make JFFS2
work, but the hint wasn't enough for me to understand how to make it happen
(and I don't yet have a CF to experiment with, altho' I'll be correcting
that in the next week or so)...
