I was definitely getting concerned over the number of different functions inside each if(...SYS_foo){} statement.

Yeah. That sounds good. The original patch should probably not be committed then, since it'll just get changed again Real Soon Now(tm). ------------------------------ Message: 2 Date: Thu, 20 Apr 2006 10:40:48 -0600 (MDT) From: "M.

Agreed. I think I made that point a little later in my post. The big difficulty here is testing the driver after the changes to make sure that no unintended bugs have been introduced.
