Thank you so much, Chris, I'll try it out a bit later tonight.
However, if you don't mind, may I offer some additional info?
Looking over the diff, I see you commented out the set_vscale call
under certain circumstances (as per other posts here):

}

While that will cure the symptom (and my dmesg output indicates that the
related print statement never occurs until changing to the tuner so it's
also relatively safe), I believe the cause of the problem is elsewhere.
An excerpt from my knoppmyth forum post dmesg output, with unimportant
lines removed:

"x580"???

Something is setting the VSC value incorrectly before the line you
commented out. I'm clarifying that just to suggest that commenting out
the line might return as a different bug later and discovering the cause
of the mis-set VSC might be worth it... :)
But again, very very pleased with the driver set. You do rock.
