I agree.
If cx23885 module could handle suspend/resume, we wouldn't need all this 
mess.

Since we are talking about this module, I quote from another of your 
messages:

> P.S. You have explicit modprobe cx23885. Does it mean that this module is not autoloaded when udev discovers the device?

The module is autoloaded when system boots.
But if I (after having moved away the script from 
/usr/lib/systemd/system-sleep/)

rmmod
systemctl-suspend
resume pc

the module is not loaded.

When I used pm-suspend, remove and reload was managed from the line
SUSPEND_MODULES="cx23885" in /etc/pm/config.d/modules

And now from rmmod and modprobe in my script.
By itself... no load.

To watch television, kaffeine seems very good to me.
