The acpi data doesn't matter at all for the boot screen, the vgabios
doesn't look at it.

seabios loaded+initialized the vgabios (from the pci rom bar of the vga
device). Which slot the vga is installed at should not matter at all.
seabios scans the pci bus and should find the vga with no problems no
matter where it is.

Seems to have worked fine ;)

At this point you should see the seabios banner at the vga screen.

As it should be.
Now the questions is why it doesn't work for Tiejun ...
Anything in the logs?
