There is no reason not to have two drives on the same channel (you 
cannot have more than 2); in fact, if you buy a new drive, you do want 
to put it on ATA/100, to get maximum speed.

The ATA hard drive is managed by an ATA controller. The controller can 
be on the motherboard, on a separate card, or in an external enclosure 
(external drives). Older controllers cannot access more than 128GB on 
any single device; that's why older machines or enclosure cannot "see" 
more than 128GB on 200GB drives, and a 200GB drive formatted with an 
older controller will only show as 128GB. Newer (48-bit capable) 
controllers can use much bigger drives. On the Mac, a few additional 
conditions must be met to use drives bigger than 128GB, but all Macs 
released since June 2002 (including yours) meet them.
