I've been getting this message since, oh, the dawn of time or so.
I finally worked up enough curiosity to attempt to figure out what the
mysterious 7f header is, but the PCI specs require money.
So, anyone out there happen to know what header 7f is, and why the
kernel doesn't recognize it?

Sorry, I have no idea. It's a Compaq Deskpro 4000 5133 from 1998 or so
that I obtained second-hand, with no documentation, and neither the
Compaq website nor an inspection of the motherboard has anything useful.

According to the PCI 2.2 spec, bit 7 indicates a multifunction device
(=0 or single function in your case), bits 6:0 indicate the header
format. 00=normal device (standard layout), 01=PCI-PCI bridge,
02=CardBus bridge, all other values are Reserved.
