Thanks a lot. 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.

Best regards...
