The raw SMBIOS tables that Linux exposes in /sys/firmware/dmi
are restricted to being readable by root only. If running as
non-root access is still permitted by fields that have been
pre-parsed by the kernel in /sys/class/dmi, most of which are
world-readable. This allows the daemon to load most HWIDs even
if running as a non-root user, as is done on Chromium OS.
