For those that like to use the rivafb at the console with 1024x768 Resolution and 70Hz Screenrefresh.
The patch I found yesterday will not solve the X -> console -> X problem but it's a nice thing if U use your linux-box in console mode. With the consolefont I'am using (lat9w-16 for western europe) it gives me a resolution of 128x48 characters.
I've prepared the kernel as follows:
Code:
Console drivers --->
 [*] VGA text console
 [*] Video mode selection support
 Frame-buffer support --->
  [*] Supporrt for frame buffer devices
  [*]   nVidia Riva support
  [*]   VESA VGA graphics console
  [*]   Advanced low level driver options
  [*]     8 bpp packed pixels support
  [*]     16 bpp packed pixels support
  [*]     32 bpp packed pixels support
  [*]   Select compiled-in fonts
  [*]     VGA 8x8 font
  [*]     VGA 8x16 font


The patch I mentioned above is this one:
( Igot it from here: ( http://alm.linuxfreak.nl/ )
