Hi Jon,

A few minor things I found:

The last sentence reads a little funny to me, maybe something like:

By distributing binary-only modules, you make it harder for you and your 
users to get support.

To me, this sort of implies that all reverse-engineering is improper, which
is not what you meant to say, I don't think.

"At this time" sounds like you are saying "now", "At that time" perhaps?
(maybe too picky)

The comma after "patch" seems confusing.

do you mean that Linus is a general?  or should that be "general rule"?  It
could work either way.

the last clause sounds like developers *will* avoid the list, maybe:

"who be best placed"?  who will be best placed ...

should lockdep have a period?

where there are testers, there are bug reports.

"run into internal limits"?  but, "runs into internal limits" doesn't seem
quite right either. 

hope that helps,

jake
