Greg,
Yes, admittedly this whole thing has gotten a little messy :P sorry for all the confusion.
I've finally spoken with Hartley about how to best clean this driver, and so I will submit
a final patchset to you as soon as I finish up with it.  Until then, please just disregard
all prior patches to hwdrv_apci1564.c from me, as the one I send next will supersede all of them
and I will clearly mark it as such for you.

Thanks,
Chase
