I guess that means that every product that has a tuner which
implements the sleep callback is broken.  And yet this is the first
case I've heard a user complain, which makes me wonder how big a
population is out there that is using scripts to control the tuner.  I
suspect most people are just using applications like MythTV, xawtv or
tvtime, which won't have these issues.

I don't intend to come across as argumentative, but if we haven't
heard a massive outcry about this by now, maybe nobody actually cares
and thus we shouldn't spend the time to build a whole infrastructure
to preserve the driver state across the low power mode.  Those people
who really do care can just disable the power management with a
modprobe option.
