Thanks for all the replies; 

I am using the O'Reilly book - but I'm kind of stuck using the semantics
that the driver's original author used. The whole effort is so we can
experiment with some hardware rather than for final release, so we don't
want to spend too much effort reengineering anything we don't have to.

Heh. I missed the part in LDD that mentions kmalloc regions being
unpageable.
