I'm going to get an Asus PC-DL with an onboard Promise PDC20378 Serial ATA

The mobo also has two ATA100 ports.

Is it possible to use only the PATA from the promise ? I have no
SATA drives now, but I could use the ATA133 port.
Is there any PATA driver that works with the promise, even if I
don't see or disable the SATA ports ?

The only way to use the PATA ports is to use a driver from Promise. libata doesn't support PDC203xx PATA ports at all, regardless of configuration.

Technically speaking, libata needs to be modified to support two different types of "host operations". Once that internal limitation is removed, adding support for the PATA ports is easy.
