I am in contact with the upstream author (of this tarball): They do not have access to a G45-based chipset, so we are currently looking into options for the future. There is currently no home page.

I think it makes sense to point people to the right documentation for at least libreboot and coreboot, and refer them to their BIOS supplier for other instructions. OTOH, I do not feel that the package description is the right place to do this. Where would such instructions normally exist on GNU/Linux machines? > I'm guessing that your card identifies as an Intel=C2=AE GMA X4500MHD.=20 > Is that correct?
