>Description:
	The hptrr(4) driver grabs the Marvell 88SX6081 device,
	and the atapci(4) driver fails to attach.

--- dmesg with htprr(4) in kernel ---
hptrr0: <sx508x> port 0xd800-0xd8ff mem 0xdec00000-0xdecfffff irq 16 at device 0.0 on pci3
hptrr: adapter at PCI 3:0:0, IRQ 16

>How-To-Repeat:
	Try to boot kernel with hptrr driver on a box that has
	Marvell 88SX6081 SATA300 controller.
>Fix:
	Workaround: disable hptrr in kern conf file and rebuild kernel.
