   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.

WBR, Sergei
