I wrote the code, and can assure you that the BIOS in the message is referring to the ROM BIOS.

Nope.
>The revision 2.10 refers to a revision of the pci bus architecture.
Nope. It refers to the PCI BIOS specification implemented.
>The reason your AMI BIOS version and AHA version isn't reported is simply once >the linux kernel is booted it doesn't use BIOS,
Nope. Certain 32-bit interfaces, such as that provided by the PCI BIOS, are used after bootup. The PCI BIOS code is used for probing and a few post-mortem checks.
>(note there is a section of >the kernel that is called BIOS, but it doesn't use any of the computer's bios). Nope.
