vmode for resolution, using values available in nvvideo's manpage
cmode for color mode (bit count works).

in reference to the nervous text, I get this on my PDQ when the mclk is
set incorrectly.  this can be specified using the mclk: param.  my
cmdline is "video=atyfb:vmode:14,cmode:32,mclk:100", but I am aware that
earlier systems, even wallstreets use smaller mclk values.  the
default/autodetect in the kernel does not work for me.  could try 83 or
60, two other fairly successful values IIRC.

Hope this is helpful.
