Some devices like the Fujitsu Celsius W380 do contain
a working sch56xx hardware monitoring device, but do
not contain the necessary DMI onboard device.

Do not check for the presence of an suitable onboard device
on these machines. The list of affected machines was created
using data collected by the Linux Hardware Project.

Tested on a Fujitsu Esprimo P720, but sadly not on a affected
machine.
