kernel-parameters.txt
At first, this sounds like an issue that might be attacked from a "disable the screensaver and any power management" angle. However, here's what turns up regarding acpi when I grep the 'kernel-parameters.txt' file on my 2.6.35 kernel - maybe something here will interest you, and if so, check out your own local version of this file in your kernel source, or Google it, to get the syntax & parameters of the option(s) which interest you:
Code:
