ACPI support?

Hello All,

I have had a problem detecting the network card on my notebook when ACPI
is enabled for a year. The problem still exists in 7.1-RELEASE.

with ACPI:
...
bge0: <Broadcom NetLink Gigabit Ethernet Controller, ASIC rev. 0xb002>
irq 17 at device 0.0 on pci8
bge0: 0x10000 bytes of rid 0x10 res 3 failed (0, 0xffffffff).
bge0: couldn't map memory
device_attach: bge0 attach returned 6
...

without ACPI:
...
bge0: <Broadcom NetLink Gigabit Ethernet Controller, ASIC rev. 0xb002>
mem 0xf3000000-0xf300ffff irq 17 at device 0.0 on pci8
miibus0: <MII bus> on bge0
brgphy0: <BCM5787 10/100/1000baseTX PHY> PHY 1 on miibus0
brgphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT,
1000baseT-FDX, auto
bge0: Ethernet address: 00:1b:24:ca:a0:aa
bge0: [ITHREAD]
...

It seems that some resources are disabled by ACPI and should be enabled
first.

Here is dmesg from linux:
...
tg3 0000:08:00.0: enabling device (0000 -> 0002)
tg3 0000:08:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
tg3 0000:08:00.0: setting latency timer to 64
eth0: Tigon3 [partno(BCM95787m) rev b002 PHY(5787)] (PCI Express)
10/100/1000Base-T Ethernet 00:1b:24:ca:a0:aa
eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] WireSpeed[1] TSOcap[1]
eth0: dma_rwctrl[76180000] dma_mask[64-bit]
...

What changes should be made to enable these resources and where, in the
device driver, acpi or pci code or both?
Is there something similar already done?

Best Regards
