The issue can be reliably reproduced on my E-450. I bisected it to:

----------
commit f9a37be0f02a943d63e3346b19f9c9d8d91826cb

    x86: Use PCI setup data

    EFI can provide PCI ROMs out of band via boot services, which may not be
    available after boot. Add support for using the data handed off to us by
    the boot stub or bootloader.
----------

Looks like your guess is correct.

Additional notes:
- this machine boots in EFI mode as well (via CONFIG_EFI_STUB)
- attached my video BIOS for reference
