Comment 287 for bug 121653

I made the same but shorter comment in bug #202814. Thanks tip of pm-suspend to get this working Bernhard :)

So after messing around it seems it's because acpi-support isn't used at all and pm-utils is. So /etc/apci-support does not do anything!!!!
See /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux (Assuming this is called)

Calling "pm-suspend" works since it's called with no quirks (see pm-suspend --help). But hal on my machine has 'power_management.quirk.vbe_post = true' because of 20-video-quirk-pm-apple.fdi changing it to false fixes resume/supend from System->Quit "logout window"
You can check with lshal |grep quirk and see what quirks is set and change the corresponding fdi files for you machine.

This bug is caused by either:
  * Hal quirks is wrong for fglrx platforms with kernel 2.6.24.
  * Hal is supposed to use acpi-support on ubuntu but patch isn't applied ?

PS
in
/usr/lib/pm-utils/defaults
I also had to set
SUSPEND_MODULES="ath_pci"

keeping network working. Since madwifi sucks too ;)
