I don't know about the cards you just named, but in general PCI drivers in Linux are written in an architecture independent way. Things like interrupts and CPU usage are handled in a portable way. PCI drivers generally break on I/O space handling: the PC is one of the rare architectures that has a separate I/O space. Alpha, Sparc, ARM, and many others use memory mapped I/O. If the driver breaks, it usually is quite easy to fix it by using the correct translation functions. Have a look in the file /usr/src/linux/Documentation/IO-mappings.txt for more details.
