Thanks very much.  I do have the SuperSavage chipset in my T23.  With
your note in hand I went poking about my kernel config file and found
the bit I've copied below.  The Savage frame buffer is not enabled.
So do I assume correctly that if I am going to enable the Savage
frame buffer I should comment out the references to VESA_FB,
VESA_TNG?  I'm also assuming that the console font reference compiled
in the kernel will be overridden with the console font in rc.conf.
Is there any advantage in leaving the default mode at 1024x768 on a
1400x1050 display when the font size can be controlled by selection
in rc.conf?  John
