Interesting what you say about stack size.  I've experienced a particular
notebook and driver that would hang quietly very easily, while
NDISwrapper was being used.  I asked the developer why he didn't
code it so it produced a kernel stack dump.  Is the symptom of
a stack overflow that it will not produce a stack trace when
the kernel hangs?  I had kinda assumed the NDISwrapper developer
wasn't using the proper error handler for kernel drivers.
