I guess the latter. Although PC peripheral designers have done a lot of
stupid things, so I wouldn't be surprised if there wasn't any way. Sane
chipsets have a way to do this.
I guess something with a ne card should dump the CIS structure... if there
is a sane tag to look for, it should be obvious.
