Idea for MTD CF-IDE
On the linux-mtd page ( http://www.linux-mtd.infradead.org/ ), it states "to the best of my knowledge [CompactFlash] doesn't have any alternative method of accessing the [raw] flash". Although this is true in the general case, it may be possible on some cards. For example, on the last page of the Samsumg ATA flash controller reference design manual, there are extensions to the ATA commands that allow access to the raw flash.

I think this means that someone could write an MTD driver for Samsung CF cards, allowing JFFS2 to run 'natively' on the card. It seems pretty straightforward to me, but I don't have time to work on it. I'm hoping that someone here gets a hankering to implement it, because I'd like to use it. ;)
