After doing some more research i decided to NOT install HAL, as i do
not want "a large monolithic unmaintainable mess" on my system =)
HAL has been removed fully from the boot process in Ubuntu 10.04
according to this link:
https://wiki.ubuntu.com/LucidLynx/TechnicalOverview
The following link also explains that HAL is no longer involved in
device configuration with 10.04:
https://wiki.ubuntu.com/X/Config/Input#Input%20Configuration%20with%20udev%20%28Ubuntu%2010.04%29
According to your link about debugging Gnome Power Manager, HAL has
been deprecated since Ubuntu 9.10
https://wiki.ubuntu.com/DebuggingGNOMEPowerManager#Debugging%20procedure
It seems that pitivi still depends on HAL, this might be the reason
why HAL is still installed default on 10.04:
https://wiki.ubuntu.com/Halsectomy
I have tried to download the latest Gnome Power Manager source and
compile it to a deb that i installed on the system, after doing that
the "Either HAL or DBUS are not
working!" and the "proxy-status is invalid for instance" warning
disappeared from the xsession-errors file, but i don't want to
manually update packages on my system so i just stick with the version
from the repository and ignore the warnings in xsession-errors.
