I left that VGA device detection code, even if the VGA BIOS image is
loaded from flash, just to make sure.
I'm pretty sure the device must be enabled prior to start VGA BIOS,
otherwise VGA BIOS won't see the device either.

If you booted Linux from PCBIOS, you see the VGA device in lspci.
But with current LinuxBIOS, you don't.
Some work is needed to enabled it.
