_SUN is a number that the system vendors thinks will
mean something to a human. Eg it may correspond
to a number painted on the outside of a machine.
It doesn't necessarily have anything to do with electrical
or logical slot numbers on a PCI bus, or any other bus
for that matter.
SMBIOS and ACPI BIOS are independent features of a BIOS.
You can have one, the other, both, or neither.
