You know that you don't have to know what it is to test it? And if you
are that curious, googling for S3 and S4BIOS would have given that
information faster than the time you hopefully took to write this mail.

Let's look at the CC list. Hm. It might be i386 specific. Let's look at
the subject. It might need ACPI. Given the history of arch/i386/acpi,
any NetBSD release will give you that. If you would actually consider to
be helpful, you would of course try it with a HEAD or jmcneill-pm kernel,
but to find out whether the BIOS claims S4BIOS support it is irrelevant.
