I'm sorry, I've just noticed that I haven't changed the value of
realbits in acpi_als_channels. This makes me wonder what would be the
proper value, given that this is a generic driver and all the
information I have are those in the ACPI specification (which states
what I reported here above).

Should I just set realbits to 32?

Thanks,
Gabriele
