On at least one system, the GET_SPEEDSTEP_FREQS call to the BIOS
returns obviously incorrect data (0 and 4 MHz...). So, check whether
the results look sane, if not, use the already existing workaround
for ancient speedstep systems. Thanks to Pierre Maziere for reporting
this issue and testing the fix.
