Comment 8 for bug 73266

Acer Ferrari 4005 WLMi, BIOS 3A19, running Edgy.

With standard kernel boot options (command line is root=UUID=e9c019e5-d78a-4cc0-8c4a-129eadbe0e3b ro quiet splash), g-p-m applet never displays. Battery Charge Monitor applet always shows AC power, even with no AC connected. However, CPU frequency is scaled down to 800MHz when I unplug the AC. Some pertinent command line output while on AC:

jtait@ferrari:~$ acpi -V
     Thermal 1: ok, 77.0 degrees C
  AC Adapter 1: on-line

And while on battery:

jtait@ferrari:~$ acpi -V
     Thermal 1: ok, 68.0 degrees C
  AC Adapter 1: off-line

And while switching between the two:

jtait@ferrari:~$ lshal -m

Start monitoring devicelist:
-------------------------------------------------
acpi_ACAD property ac_adapter.present = false
acpi_ACAD property ac_adapter.present = true
acpi_ACAD property ac_adapter.present = false
acpi_ACAD property ac_adapter.present = true

Note that with these boot options, my IEEE1394 interface and Broadcom BCM43xx wireless NIC don't work either. Having looked at the dmesg output from boot, I've tried booting with the irqpoll and pci=routeirq options, which seems to allow all these things to work normally.
