Bart, here's a driver I've been keeping out-of-tree for the past couple of
years.
This is for the Delking/Lexar/ASKA/etc.. 32-bit cardbus IDE CompactFlash
adapter card.
It's probably way out of sync with the latest driver model (??), but it still
builds/works.
I'm not interested in doing much of a rewrite, other than for libata someday,
as I no longer use the card myself.
But lots of other people do seem to use it, so it might be nice to see it
"in-tree".
