	Ok, tested it.
	First comment : the patch did not apply cleanly here. It's
fairly possible that I didn't had the right stir version to start
with, or that Dave's version is already patched, but you may want to
look at it.
	On hunk fail : @@ -909,45 +893,42 @@

	Second : Performance and stability is much better, but it's
still easy to make the driver fail at FIR. A summary of my perf
testing is below (you can compare to the numbers on my web page with
dyn-perf.txt). Don't get me wrong, I'm not criticising your work, and
I consider that if it works at all it's almost a miracle, but you may
want to know how it goes ;-)

	Otherwise, yes, just push that to Dave ;-)

	Jean
