This doesn't work anyway, it stops pmacs from hanging but still there is
a long wait, which you can ^C interrupt.

I believe this is because since there is the RTC clock, the GENERIC_RTC
code will not be called or something.

That would be a solution, but i think i will look again at my previous

Anyway, on pegasos 2, i have the problem that CONFIG_RTC works fine, and
the clock is set, but only _later_. This has as result that the clock is
wrong when it is the time for filesystem checks, and thus filesystems
are checked each time.
