I too have a BP6, and I've started looking at this.  I *think* the HPT366
is configured as two single-channel controllers (hence two functions).  At
least this is how it looks from the BIOS device listing.

Last year I got hold of some patches for the Linux driver which include
code for the HPT366.  I haven't got very far (although I've only spent a
couple of evenings on it up to now):

    Fixed pciide driver to attach HPT366 even though it's "miscellaneous
    mass storage".

    pciide now claims that the controller doesn't support bus-mastering DMA.
    It then tries to attach it in compatibility mode, and panics shortly
    after that.  

At present the BP6 machine is on 1.4, but I intend to install -current in
the next week or so and see if I can make any progress - unless someone
else is already working on the HPT366.

I may also try installing Linux, just to make sure that the driver source
I'm relying on as documentation does actually work. :-)
