I believe, that the R5.3 acpi driver is unable to turn power on after a certain amount of time passed by (just like 5.2-CURRENT-20040408). SuSE Linux was able to do so at least one year ago.

I would prefer an acpi driver, that is able to order the power on procedure at the time specified in the BIOS... I am ready and able to test certain patches.
