The via driver used to fool some people into thinking that it was running 
their provided or a builtin modeline, while, when lucky, all it cared 
about was H/VDisplay.

Now it's no longer fooling anyone much, it's just restricting to what it 
does know, and that is currently what the VT1622 code adds itself. This 
is quite some distance ahead of previous behaviour. Further improvement 
will require a sisctrl like application, which is one of the many things 
on my TODO list.

The list of available modes is provided in the manpage. I have reproduced 
what was accepted by your X, and reported in your log, above.
