Already fixed it. >>From what you tell me, do I have to deduce that the solution depends on the ACPI developers? I have been looking the latest unstable kernel, 2.5.70, and I've seen there is something like 'Emulate /dev/rtc', so maybe it's going to be left like it is now? It would be a problem, though, because of how the default scripts (at least in Debian) are written, but I guess that the Debian people are more than aware of the problem.
