I suppose that hald is reading the information from sysfs or /dev/mem as
root before dropping the root privileges.

There have been many people complaining about the inability to read uuid
and serial numbers as non-root users over the years. Their complaints
have always been ignored or turned down so far and I can't see this
changing. UUIDs and serial numbers are considered private information
which should not be readable by everyone by default.

If you want these values to be world readable on your system, feel free
to chmod them at boot time. The permissions defined in the dmi-id driver
are only the default permissions, nothing prevents you from changing
them at run-time (as root, obviously.)
