If you have sample XFree86 modelines, you can use the utility
modeline2fb to convert them to entries compatible with /etc/fb.modes.

Or you can use the VESA GTF (Generalized Timing Formula).  There
are several utilities as well as online calculators that will generate mode
timings for you based on the GTF.

You can easily do a google search for both of them.

The rivafb driver uses DirectColor and several applications have
difficulties with this mode since they assume that Truecolor and Directcolor
are the same.  (Most applications are used to Truecolor).

If I have time, I'll see what's wrong with fbxine.

I get the same thing to, not just rivafb.  Similarly, once I have time, I'll
try to examine this.

I already submitted the patch.
