In 2.6.17-rc3 pcmcia_request_window(&link, ...) is correct.

On the cards I tested this with, the memory window wasn't much bigger 
than the registers in which ide_cs is interested.
But you're right, the card could also have a really big memory window 
with the registers at the beginning - so I better change this to a fixed 
length of 16 Bytes.
