The commit in:

  http://mail-index.NetBSD.org/source-changes/2008/12/29/msg214585.html

almost fixes the screen clearing problem.  (The screen is cleared with a
black background, even with WS_DEFAULT_BG=WSCOL_LIGHT_WHITE in the kernel
config).  It is more readable now though.

For the attributes, the current code only supports reverse video (see the
handling of 'm' in src/sys/dev/wscons/wsemul_sun.c:wsemul_sun_control).
Bold and underline support need to be added (they are already supported by
the VT100 emulation).

Thanks,

J
