Comment 28 for bug 505452

On my Eee PC 1005HA:
- eeepc_laptop.ko does not load with the out-of-the-box configuration
- with GRUB_CMDLINE_LINUX="acpi_osi=Linux", the module loads correctly

As for what happens without/with the module:

Key Without With
---------------------------------------------
Sleep yes yes
Wifi no yes
Touchpad no yes
Screen size? - -
Bright+ yes yes (no popup)
Bright- yes yes (no popup)
Screen off yes no
Ext.display no yes
Sys.monitor? - -
Mute no yes
Volume+ no yes
Volume- no yes

The module should obviously load without tweaking /etc/default/grub, but the fact that it breaks "screen off" and messes with the behaviour of the brightness keys is a bug in itself. Should I file this as a separate bug? Is there any info I can provide to help fix the first one?
