(I'd prefere not to). I know I won't have swap on the card (I'll
recommend a micro-drive if I have to have swap). My immediate goals is
to have a small memory usage foot print. I'm going to start off by
setting the FS to read-only and see if anyone screems. I'm currently
using a 2G CF card but at the moment I'm not using more than 256M. I
doubt I can trim it to fit below 128M so I'm stuck with 256M.


There are better filesystems for flash than ext3. if you want to use
ext3, you need the "noatime" option. You could try something like jffs.
Read about it on http://en.wikipedia.org/wiki/JFFS

JFFS is useless for CF cards. JFFS does its job on plain flash devices only.
