Thanks Clemens!, this explains my lack of success with the PDC20378. 
Jeff Garzik (who apparently heads work on libata) assured me that PATA 
support for sata_promise is not in 2.6.18. The page above confirms that 
there is just *no* PATA support for the PDC2037X in 2.6.18. So my 
remaining question is, being unfamiliar with kernel hacking should I 
just apply a sort of rejmerge approach?:

    a) open linux-2.6.18/drivers/scsi/libata-core.c in emacs
    b) substitute the patch (indicated as lines preceded by +++) for 
lines to be removed (indicated as preceded by ---)
    c) recompile the kernel, redo grub, and
    d) reboot?
