Re: I havent got the bandwidth yet @Kiwi
There are some. I have a PCI card based on a Broadcom chipset, inherited when I got given a Shuttle compact PC, where I could not find any support, either pre-compiled or in source, that would work to get the card to function in Linux (specifically Ubuntu 12.04 - it was a few years ago).
But then again, the card was so obscure that it took an absolute age to find some drivers that worked in Windows XP, as well.
I also had some problems with the Atheros wireless chip in the original EEE PC 701 with Ubuntu, because it took some time for the particular chipset to be supported in the repository.
