Yes, except the fact, we wouldn't see anything :) -- I'll add inside the 
if a return statement or something to disallow the oops to flood screen.

Also, it doesn't happen regularly. Mostly several first tries after cold 
start. I hope this is a regression and not a HW problem, but it emerged 
after switching to 2.6.29-*, I will keep you informed.

Thanks.
