   1 From: Dirk Mueller <dmueller@novell.com>
   2 Subject: setfont breaks first Xserver start
   3 References: 302010
   4 Patch-Mainline: No
   5
   6 The patch prevents setfont from accessing vga registers on the card when
   7 the card is in graphics mode KD_GRAPHICS as we assume, that someone else (ie.
   8 the Xserver) is in charge of the HW in which case accessing the vga registers
   9 may (at best) have no effect (not even the desired one) or (at worst) interfer
  10 with settings the graphics driver has made.
