Hello Daryl,

I did not read the hole thread but I think Michael is right when 
pointing to permissions and sudo will be the solution.
I'm using mythbuntu 12.04 and had to use sudo: search for sudoers in 
http://www.mythtv.org/wiki/ACPI_Wakeup

I'm using the mythwelcome-mythshutdown-solution, and had to do several 
configurations.
(Bios, mythtv-setup, mythwelcome, setwakeup.sh, sudoers, ...)

When you are interested I can give you more details of my setup. Only 
ask what you need.
