Could you send output of dmesg after boot? (Please select ACPI DEBUG in 
the kernel config to have some meaningful output in there). Does your _PRT 
table get printed?

Here I get:

ACPI: PCI Routing Table (bus 00)
  device=01 pin=00 source=\_SB_.LNKA source_index=0
  device=01 pin=01 source=\_SB_.LNKB source_index=0
  device=01 pin=02 source=\_SB_.LNKC source_index=0
  device=01 pin=03 source=\_SB_.LNKD source_index=0
  device=07 pin=03 source=\_SB_.LNKD source_index=0
  device=08 pin=00 source=\_SB_.LNKD source_index=0
  device=09 pin=00 source=\_SB_.LNKC source_index=0
  device=0a pin=00 source=\_SB_.LNKB source_index=0
  device=0b pin=00 source=\_SB_.LNKA source_index=0
  device=0c pin=00 source=\_SB_.LNKB source_index=0
  device=0d pin=00 source=\_SB_.LNKB source_index=0

You should see something similar.
