James,

you have the same controller as me (PDC20378) which
has only 1 PATA port. PATA ports support up to 2
devices per port, as opposed to SATA ports which
support only 1 device per port.
There is source code for 2.4 linux driver on Promise
web site, you can have a look.
Could you send your dmesg output?

Note that PDC2037x has a "dual master mode", where two PATA devices 
(master/slave) on the same cable can be made to look like two 
independent PATA masters, thus giving the illusion that there are two ports.
