I have a simple question.  I'm brand new to trying to make any kernel
source changes.  I'm looking at /usr/src/sys/dev/sun/ms.c which appears to
be the mouse driver for my sparc.  I have a wheel mouse attached to the
machine (via a PS/2 <=> SUN converter box) and I'm interested in having
the driver print the raw data to the screen as it comes in.  That way I
can see what codes come from the mouse (if any, don't know if the
converter box lets it through) when the mouse wheel is moved.  Then I can
figure out how to handle the wheel.  Can I just use printf in a driver
like that?  Or is there a problem with printf not knowing where stdout is?
Is there a better way of getting info like that?

Thanks
