Not sure I follow that comment, in*/out* have been the mechanisms to  
access PCI IO space for as long as I've know.

Would it be safe to assume that if I were to modify the existing

chip->port = pci_resource_start(pcidev,0);
chip->res_port = request_region(chip->port, size);

outl(chip->port+MyReg, data);

To something like:

chip->port = pci_resource_start(pcidev,0);
snd_length = pci_resource_len(pcidev, 0);
snd_port = ioremap(chip->port, length);

outl(port+MyReg, data);

I am not sure if I want to leave the outl in there, perhaps a  
different
function, or just a direct assignment?

You shouldn't have to do the ioremap, the PCI platform code should  
have already handled all of this.

What PPC platform are you on?
