It does make a difference. I've had the machine running over the week-end, and haven't had a crash in 56 hours.

After applying the setting I get some errors on reboot, no idea if they are harmful in any way (none that I have notced):

AcpiOsExecute: failed to enqueue task, consider increasing the debug.acpi.max_tasks tunable
ACPI Error: Method parse/execution failed [\\PNOT] (Node 0xfffffe00052e6400), AE_NO_MEMORY (20110527/psparse-560)
ACPI Error: Method parse/execution failed [\\_SB_.AC__._PSR] (Node 0xfffffe00052f57c0), AE_NO_MEMORY (20110527/psparse-560)
