The patch panics, although I had to apply it manually so maybe that's 
the problem, however I think I merged it properly. This is a with 
a -current from today so maybe that is the issue, I can test it with a 
specific set of code if you like.

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address	= 0x00
fault code		= supervisor read, page not present
instruction pointer	= 0x20:0x0
stack pointer		= 0x28:0xc10207c4
frame pointer		= 0x28:0xc10207d8
..
bus_generic_attach()
acpi_pci_attach()
device_attach()
device_probe_and_attach()
bus_generic_attach()
acpi_pcib_attach()
device_attach()
device_probe_and_attach()
bus_generic_attach()
acpi_pci_attach()
device_attach()
...
goes on for a while, I took some pictures instead of transcribing it 
all.. Let me know if you want them.
