Thanks, it eliminates the WARNING, but still the box doesn't work with
the "x86: add C1E aware idle function" patch applied, even with 'highres=off'.

The main symptom is that CPU loads are computed incorrectly (I got X using 126%
of CPU time from 'top', for example).  Apart from this, some processes (like
gkrellm) seem to be 'frozen' and only change their state in 'jumps', as though
they only got CPU from time to time at random.

Reverting the above-mentioned patch fixes those problems.

Thanks,
Rafael
