Even if I don't make me a lot of friends, the au1x00 driver seems to be a hack.

Most of the difference seems to be the PCI stuff, that has been removed and the access method. Shouldn't we have a driver for the chip and one driver for each access method (isa,pci,...).
The access method should handle register access and the bus abstraction.
I have a lot of problems with the au1x00 serial driver, because I use it together
with a PCMCIA serial port card.
