Well yes, in the grand scheme of things it might be nice if the kernel
RTC /dev/rtc driver was capable of being opened multiple times and that
it was possible for ALSA and other projects that may want to use it to
be able to access it via some interface from within the kernel.

Yes.

Oh its just a hack. It takes bits of the existing /dev/rtc driver and
gives it a dynamically loadable ALSA timer interface. So you can't
even have the kernel RTC driver compiled in (and unfortunately it is
not dynamically loadable).
