This is just a FYI,

I have an Acer Aspire 5672 laptop[1], which mainly runs Xubuntu, because FreeBSD doesn't work very well on it. From time to time, I test it with FreeBSD to see if the situation has improved.
The results for FreeBSD 8.0-stable are now in[2].

What can I say?

The only way I can get network interfaces (bge, wpi) working is by disabling acpi. However, I can't run the laptop with acpi disabled for longer periods of time, because it will overheat.
If acpi is enabled, and I kldload if_wpi the machine panics (page fault).

In short, this particular laptop doesn't work very well with FreeBSD.

As I can see, problem is the same as with mine TravelMate 6292. Enabling
ACPI clears resources on PCIe bridges:

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


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


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

Fixing this require significant improvement of the PCI code, which
wasn't done yet. At this moment I am using machine-specific local hack
to set proper resources there (same as in non-ACPI mode) by hands:

I tested this patch, and it makes this laptop work better. Thanks!
bge0 still doesn't attach for some reason, but wpi0 does, and it is usable now.

My patch was made exclusively for my TM6292. It may not fit your A5672.
You should boot in non-ACPI mode, copy resources of PCI bridges and
update patch using them. If you do it right, reported bridges resources
in ACPI and non-ACPI modes should be the same.

FYI: I have now tested this laptop with FreeBSD 8.1-release. The results are the same as with 8.0-stable: due to troubles with decoding PCIe bridges correctly (or somesuch) the network interfaces - wireless (wpi) and wired (bge) doesn't work. Patches to the pci code might help this, but I have not tested that yet.
As before, dmesg output are on the web page maentioned in the original post.

Update:
I have now tested this laptop[1] with FreeBSD 8.2-stable[2].
The results are the same as when it was tested with 8.0-stable.
It still needs patching of the PCIe code to get network interfaces to work.
I used a patch[3] made by Alexander Motin for a different machine, amd even if the seconfd hunk of the patch was rejected,
the wireless interface (wpi0) works.

Please try adding 'options NEW_PCIB' to your kernel config on a recent 8-
stable instead. You should not need Alexander's patch in this case.

I did, and now it works. Nice, very nice! dmesg output here:
