The SRM console gets the red and blue attributes backwards in the VGA

palette.  As a result, the colors on the video console can look rather
weird.  For example, sysinstall on the alpha has a read background.  We
can work around this partially by remapping the colors used by syscons for
the ANSI color escape sequences.  Note that screen savers and anything that
sets the colors explicitly will still get incorrect colors, but programs
such as sysinstall will now use the correct colors.  A more correct fix
would be to actually fix the VGA palette on boot by either swapping all
the red and blue attributes or by hardcoding a standard palette and
overwriting the entire palette.
