This patch uses always the adjusted video mode instead of a mix of
original and adjusted mode.

No visible side effects here, but rather than copying the "adjusted_mode"
pointer to "mode", I'd much rather see the references to "mode" become
"adjusted_mode" instead - choose a shorter name if it's too long, maybe
"adj_mode" ?

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up.  Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".
