Thanks.

True. I was already contemplating the possibility of one probe function
having to deal with different amounts of shift... But this would not
work safe in either method right now.

(Assuming the unlikely case that 7e 7e 7e 55 and 7e 7e 55 have to be handled
by the same probe function...)

This would indeed favour passing the unshifted ID buffer for such functions
to find out the amount of 7f's. If you favour that, I am game with it. But I
will resubmit the ramtron part only when the new probe is in mainline and
I have rebased my tree to it.
