xfree86/fbdevhw not sending right mode to radeonfb.c

Hi Kostas,

FYI: Well I finally figured out what was up.  It seems the first thing the
special code for "DFPValidateModes" in radeon_driver.c does is delete all
modes since the timing info is technically not needed by them for DFP.

That is just a pisser since it removes the completely valid mode I had
placed into the XF86Config-4 for just that reason.

So no great mystery but I just don't think they should do that when using

That is only part of the problem, the other is that if you change the
depth from what is used by the frame buffer it does mess up as others have
