Well, CF shows up as Just Another IDE Drive (provided it's connected
with an IDE adapter... not sure what drivers are used when it's on a
USB adapter etc., but I thik even then it doesn't get a special
driver.

No wear leveling is done in the card itself that I'm aware of,
either...there may be a block buffer or similar in the controller, but
that's minimal.

Mount it noatime at the very least, sync would also make sense.... and
ext2, NOT ext3 (though I suppose you could use an external journal,
but what would be the point?)

I've seen Linux tools for doing wear-leveling on flash over in
PDA-land, but haven't seen any of those drivers in use on the PC
side... and I boot my home system from a 512MB CF.
