Well Patrick, I was wondering if there is a website
that identifies cards (chipsets) NOT supported by linux.
I see for example FBSD users not finding drivers for
Broadcom chipsets (perhaps only specific ones).
So, to help
existing linux users and newbs, it seems
that such a website would go a long way to let people
know what are NOT supported, or partially supported
devices. It would also helps people shopping for a new
computer to avoid laptops that have unsupported chipsets.
Cheers,
JD
