I finally got my Tseng card to display at 1152 and 1280, rather than just 
1024, with svgalib, on a monitor that does HorizSync 54 and VertRefresh 
100

1.  chipset VESA (adds 1024 - otherwise it was only 800) - needed for 
Tseng and SiS and I think Matrox but not S3 or Cirrus

2.  Change HorizSync from 31.5-35.5 (low-end SVGA interlaced default) to
HorizSync 31-5 54
 (56.4 for my IBM monitor, some 15" monitors only go to 50 but will 
display 1280 with S3 anyway).

3.  Change VertRefresh from 50 90 to
VertRefresh 50 100
(Some older monitors won't support this.)

My IBM mouse works with the default power settings, but other mice have to 
have power turned off to work correctly.

I changed from microsoft to ps/2 mouse.

svgalib 1.4.3 from SW81 supports much higher resolutions, including 1600 
and possibly up to 2048, but for the more unusual combinations of horiz x 
vert dpi you will need to add your own modeline.

I will try this svgalib with SiS (which would not work at all with the 
older one from SW71) and with Matrox cards (which I think messed up the 
screen on exit from zgv.  I know some other newer PCI cards did so).
