[LinuxBIOS] epia acpi patch ( for testing only )

[Ben Hewson]

good to hear it works ok on your board. I am not to sure how to do the 
power button, but will have a look. Also need to enable wakeup events, 
or at least put some commented code in there so people can 
enable/disable the ones they want.

Thanks also for the pci dump. The differences between the original bios 
and LB appear to be mostly the same on your board also. At least the 
registers I think may be causing the problem. I'll  try setting them on 
my board and see if it helps with the hangs, not that they happen very 
frequently at the moment.
