I think the status is that it maybe runs on one specific hardware
which noone really has access to.

Suggest don't run the VGA BIOS in coreboot. We really need to change
the default. Please run the VGA BIOS only using SeaBIOS as payload.
I guess those services are to query system-specific data. Look at
what has been implemented in coreboot and SeaBIOS already for this.
