I just realised in this thread that this IBM license is incompatible with the 
GPL. So it's new to me. And even worse, it doesn't only affect the PCI code 
but also the 4xx EMAC code.

So if we have to really remove all the code with this IBM header, 4xx support 
will be in really bad shape. :-(

So it's even more important to know, if such files as this 4xx PCI code, which 
has nearly nothing in common with the original IBM code, can move to GPL. Not 
sure how to solve this issue though. Perhaps we should ask somebody at IBM?

Best regards,
Stefan
