New Revision: 331191
URL: https://svnweb.freebsd.org/changeset/base/331191

Log:
  MFC r315986:
  
  Fix 3 entries in mode tables related to mono and 90-column text modes.
  Newer VGAs don't support any mono modes, but bugs in the tables created
  2 virtual mono modes (#45 90x43 and #112 80x43) that behaved more
  strangely than crashing.  90-column modes are tweaked 80-column ones
  and also fail to work on newer VGAs.  #45 did crash (hang) on some
  hardware.
