I'd forgotten that it was in BROKEN state.
The issue was that the driver was fully functioning, but it clashed with
the graphics aperture driver - both use different registers within the
same PCI device - it was marked broken on the basis that the with the
kernel PCI device allocation code as it stood at the time, if the
i82443bxgx_edac driver was loaded first, the graphics aperture
configuration driver could not also be loaded, and this could break
As far as I remember, it was left was that Greg KH had said that he was
working on a change to the PCI device allocation code which would allow
both to coexist. I don't know if that happened.
The last CPU which used these chipsets (130nm Pentium III) were released
in 2001. I don't know when they were produced up until.
On that basis, I don't see a problem with removing it, but if there's a
preference for me to fix it, (and if I still have some old hardware
somewhere that I can test it on), I'll be happy to do that instead.
