Many systems do not provide a DMI table and on these systems a warning, such as the following, is printed on boot ...

If DMI support is enabled in the kernel, there is no simple way to detect if a DMI table is table or not. Note that the variable 'dmi_available' is not exported and so cannot be used by kernel modules.
We could fix that, or provide an accessor function? Or only warn if we're on an ACPI system (which we can check from a module). This really does feel like something we should be warning about on systems that are supposed to have DMI information available as standard.
