This URL at Apple show the block diagram of the iBook and the Airport card
is shown on the same ATA bus at the CD-ROM.

http://developer.apple.com/techpubs/hardware/Developer_Notes/Macintosh_CPUs-
G3/iBook/index.html

The diagram of the PowerBook shows it coming off the Key Largo chip and not
the Cardbus bridge but doesn't say anything about ATA.

G3/PowerBook/index.html

Is the PC card spec close to or based on ATA? It makes me wonder, it seems
strange for Apple to go this proprietary route for seemingly little gain.
But hey, we are talking about Apple here.
