The new version of Syscons distributed with FreeBSD EPSILON has
very poor support for HGA/MDA display adaptors. I seem to recall that
the old 1.x version of Syscons had better support than the current one.
Though my memory could be faulty :)
Anyway, the bug is that on a HGA display the driver has no
visible cursor. This makes using vi or any other text editor very
interesting :) The fix is very simple. It moves a badly placed "if" to
where it belongs.
