[LinuxBIOS] Intel 440bx

[Corey Osgood]

If you get a chance, there's a note in the 440bx spec update that is of
some minor interest:

13. Abort Disable Test Mode Configuration Bits
    Intel Reserved Register bits at offset F4h, bits 29 and 30 should be
set to 1 for normal operation.

It could be (most likely) is nothing, as my current lspci shows it not
being set, but it might just help. Damn reserved/undocumented registers.
