Nice :-) .
One thing that comes to mind... are these values initialized before
startrtclock() is called?

In the diff I posted earlier, the autoconf.c::cpu_configure() function
is patched to call bios32_init() as the first function -- before
starrtclock(), so the SMBIOS is initialized and the other init
functions, startrtclock in this case, can use the smbios_xxx()

In this case the smbios_get_string() function is used; all of this
SMBIOS functions are available in the netbsd-4 (in fact the patch is
against the netbsd-4 branch) so the patch can be applied to NetBSD 4.
A diff for -current should use the pnp_get_platform, then...
