I think I figured it out, however it seems that although my
modeline includes 'composite'
DisplayModePtr mode->Flags & V_CSYNC
does not evaluate to true. I assume as long as the 'composite' keyword is
found on the modeline, the flag should be set, right ?
I need to add some debug messages, but this seems a little strange. Is
there something else that needs to be configured, like telling that the
driver actually supports the composite keyword on the modeline ?
On a different note, the latest X release does not seem to work on that
chip. I just get a blank screen. So I started hacking on Xorg 6.8.2 to
test this stuff. I figure XFree86 4.5 should work, but 4.6 does not.
I'll provide patches to all and note on which version it was tested of
course, once it works :-)

The driver currently ignores the V_CSYNC mode flag, so you would need to
come up with a source patch to change that.
I'd be happy to provide a patch, if I can figure where to put that. Since
it is only a matter of setting one register it should be simple enough. I
have (had?) no idea where to start, I'll grep for V_CSYNC and see...
An appropriate spot for such changes would be after calls to vgaHWInit(),
which, in this case, is in SMI_ModeInit().
