FWIW, I started a new thread[1] on freebsd-mobile, to update the status
now after FreeBSD 7.1 has been released

Interesting. For my laptop, it seems that these bridges have the
problem:
pcib2: <ACPI PCI-PCI bridge> irq 17 at device 28.0 on pci0
pcib2:   domain            0
pcib2:   secondary bus     2
pcib2:   subordinate bus   2
pcib2:   I/O decode        0x0-0x0
pcib2:   no prefetched decode
pci2: <ACPI PCI bus> on pcib2
pci2: domain=0, physical bus=2
pcib3: <ACPI PCI-PCI bridge> irq 16 at device 28.1 on pci0
pcib3:   domain            0
pcib3:   secondary bus     3
pcib3:   subordinate bus   3
pcib3:   I/O decode        0x0-0x0
pcib3:   no prefetched decode
pci3: <ACPI PCI bus> on pcib3
pci3: domain=0, physical bus=3

and also these:

pcib4: <ACPI PCI-PCI bridge> irq 18 at device 28.2 on pci0
pcib4:   domain            0
pcib4:   secondary bus     4
pcib4:   subordinate bus   4
pcib4:   I/O decode        0x0-0x0
pcib4:   no prefetched decode
pci4: <ACPI PCI bus> on pcib4
pci4: domain=0, physical bus=4

pcib5: <ACPI PCI-PCI bridge> irq 19 at device 28.3 on pci0
pcib5:   domain            0
pcib5:   secondary bus     5
pcib5:   subordinate bus   7
pcib5:   I/O decode        0x0-0x0
pcib5:   no prefetched decode
pcib5: could not get PCI interrupt routing table for \\_SB_.PCI0.RP04 - AE_NOT_FOUND
pci5: <ACPI PCI bus> on pcib5
pci5: domain=0, physical bus=5

bge0 (the wired interface is on pcib4:

bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x4201> irq 18 at device 0.0 on pci4
pcib4: bge0 requested unsupported memory range 0-0xffffffff (decoding 0-0, 0-0)
bge0: 0x10000 bytes of rid 0x10 res 3 failed (0, 0xffffffff).
bge0: couldn't map memory
device_attach: bge0 attach returned 6

and wpi0 (the wireless) is on pcib3:

wpi0: <Intel(R) PRO/Wireless 3945ABG> irq 17 at device 0.0 on pci3
wpi0: Driver Revision 20071127
pcib3: wpi0 requested unsupported memory range 0-0xffffffff (decoding 0-0, 0-0)
wpi0: 0x1000 bytes of rid 0x10 res 3 failed (0, 0xffffffff).
wpi0: could not allocate memory resource
device_attach: wpi0 attach returned 6

With acpi disabled, the bridges shoiw up like this:
pcib2: <PCI-PCI bridge> irq 17 at device 28.0 on pci0

Perhaps I should try to patch my pci too.
