pci_mem_find: expected mem type 00000004, found 00000000


With -pm kernel, where the only change is the diff I sent earlier (to make
agp_i810 call agp_intel), and in pci_mem_find aprint_debug("void region")
changed to printf, I get:

pci_mem_find: void region


When I change agp_map_aperture to include PCI_MAPREG_MEM_TYPE_64BIT
in the type parameter, I still get:

pci_mem_find: expected mem type 00000004, found 00000000


When I further change pci_mem_find to completely skip the mem type
check, I get back to this

pci_mem_find: void region
