Yep. The corresponding modeline in XFree86 4.2 is:

  Modeline "768x288" 16.0 768 848 902 1022 288 290 292 312 -hsync -vsync

It's a mode designed for regular PAL TV output (through RGB-SCART) and
it works excellent with XFree86 4.2. The corresponding modeline for NTSC
looks like this:

  Modeline "768x240" 16.0 768 848 902 1022 240 243 244 261 -hsync -vsync

Hopefully, rivafb will support interlace some day and then these
modelines will also work:

  ModeLine "768x485" 16.0 768 848 902 1022 485 491 496 525 -hsync -vsync in=
terlace
  ModeLine "768x576" 16.0 768 848 902 1022 576 580 585 625 -hsync -vsync in=
terlace

(PAL and NTSC respectively.)

For some reason, rivafb will not render any of these modes properly a.t.m.
