It's totally unacceptable for drivers/ide/ as this is self-containeed driver no using IDE core for anything, so this can only fit well to drivers/block/. OTOH, CF support via self-contained driver is certainly a waste of code since IDE core and (libata) are here to drive the CF devices as well. What we need is a "normal" IDE or libata (at your option) driver.
