Sam,

Several of these are due to driver variable names not matching
the whitelisted names in modpost.  I have patches for the ones
that I have identified so far.  And I have patches for a few of
the others that are true section mismatch problems (total of 8
patches ready for now).

The whitelisted names will always be a (small) problem.
Can __init_refok be used in these cases.. or some other new
attribute, instead of forever adding to the whitelist or
modifying variable names?
