Hmmmm...  Ya know, now that you mention it, I don't think it ever
occurred to me to try running the card under Linux with the rotary
switch set to something other than the video mode I intended to use
under X11 :-).  I'm sure my thinking was along the lines of "the
switch provideth the ultimate guidance as to what video modes are
possible and/or supported by the card hardware."  At which point,
I tried to specify the chosen mode accurately in the xorg.conf file.

True enough that the card always comes up with what I assumed was
a standard 80x25 text mode screen at boot time, regardless of the switch
setting.  Given my assumption about that being a text mode, that didn't
violate the principle of least astonishment :-).

I guess I don't think enough like a hacquer...  Never occurred to me
that the switch wouldn't have some effect on the available graphics
mode for the X server.

Yeah, my eyes can't stand the 60 Hz flicker...  70 Hz is pretty much the
minimum I can personally tolerate for more than a few minutes.
