Sigh.  That's what I originally did.  There are issues in qemu with 
doing this from a driver; the SMBIOS entries are already fixed before 
the driver initialization code runs.  I did some changes to fix this, 
but the qemu folks suggested that I send it over with the firmware 
interface and do it in the BIOS.

There are some advantages to doing this with a different interface. This 
way, it's available to other firmware types; OF and uboot could populate 
device trees from this interface.  And SeaBIOS could use the same 
information to populate some ACPI PNP interfaces that can also be used 
to configure the driver.

Thanks,
