Promise SATAII 150 TX4

We are building a new box with SATA and for that we were going to
buy a couple of SATA 150 TX4 cards (PDC20318) which work well in
some other boxes we have.

However we ended up with two SATAII 150 TX4 cards (PDC40518) instead
which seem to be unsupported in both RELENG_5 and HEAD at this moment.

Adding their PCI id's to the existing driver didn't seem to be enough.

Is support for this controller in the works?

Thanks in advance.
