- changes for the grfconfig interface (provided by Ignatios Souvatzis): 

- Remove gv->{hblank_stop,vblank_stop} and use the other grfvideo_mode
    values to set ba->data.
  - Add gv->disp_flags to select interlace.
  - Not yet supported are: doublescan, sync-on-green and the horizontal/vertical
    sync polarity.
  This makes it possible to use xfree values for grfconfig.

* You will also have to write warnings in BIG BOLD RED BLINKING

* The ul_load_mon transforms these values right before loading
* them into the chip.
*
* btw, the _totals are always sync_start+1, to compute the frequencies
* correctly. (see TMS34010 manual)
* This leaves us with a single point where things are transformed,
* which should make life easier if we ever change things again.
