I am running development kernel 2.5.15 and am having some
trouble getting rivafb to display in the correct mode.

After booting with "video=riva:1600x1200-16", fbset says:

mode "1600x1200-60"
     # D: 162.022 MHz, H: 75.010 kHz, V: 60.008 Hz
     geometry 1600 1200 1600 1200 16
     timings 6172 304 64 46 1 192 3
     hsync high
     vsync high
     accel true
     rgba 5/11,6/5,5/0,0/0
endmode

But the Tux logo is all purple.  After running fbset -a "1600x1200-76",
I seem to have the correct mode:

mode "1600x1200-76"
     # D: 197.981 MHz, H: 95.183 kHz, V: 76.146 Hz
     geometry 1600 1200 1600 1200 8
     timings 5051 304 40 42 3 136 5
     accel true
     rgba 8/0,8/0,8/0,0/0
endmode

What do I need to change about my append= line in order to get
the corrent mode set at boot time or is this a bug in the
rivafb code in 2.5.15?
