Ian,

Just an comment on your renaming.

You also renamed the registers in the daqbook2000 driver in the
<driver>_REG_<name> format. Personally I prefer the format to be
<driver>_<name>_REG. That way a grep for <driver>_<name> will
return both the register and bit uses.

Currently the <driver>_REG_<name> form is not as common in comedi.
Looks like it's only used in amcc_35933.h and will be in daqboard2000.c.

The <driver>_<name>_REG form is used a lot.

Not a big deal, just a comment.
