You want to use the read{b,w,l} and write{b,w,l} macros for two reasons:
1. Accesses to registers need to be synch'ed with 'eieio' or some other
synchronizing instructions.
2. Portability of your driver if you ever should ever move it to a
different architecture and/or change the endianness in your system
