Update...

I've spent way too many hours on this now, probably 12 in the last two days, 
and still I have no solution.  This is after crashing my Zaurus an 
uncountable number of times.  I'm about to give up, simply because I can't 
waste away my time like this.  What I wanted was to make this thing clean, 
but instead I spent probably more time in hacking then I'll ever do in 
ejecting and inserting of my Bluetooth card.

I don't think I want to see another info->link or mod_timer again in my life.

I hereby commend anyone who manages to do kernel development.  Personally, I'd 
like to start throwing things out the window.

Is it 5AM already?
