The generic VGA driver doesn't work with 6326, so XF86Setup can't be used for this card. Please use xf86config instead.
With intensive generation there is a snow phenomenon on the screen. Can't remove it even if I used the fifo low/high water mark dumped from W95.
The latter point is changed. Now we use calculated values for the fifo settings, and this appears to be stable until the bandwidth required for CRT is near the memory bandwidth (dotclock*depth/8 near Mclk*32 or Mclk*64 ). In that case, you could try to use fifo_moderate, fifo_conservative or a lower dotclock.
Some video modes with high dot-clocks don't work at all, resulting on black screen. We are tracing now this problem. Lowering dotclock in that case could solve the problem.
