What manual is that? Something originating from X or from trio?

When you install the X server and create /etc/X11/XF86Config,
you should get many more modes than you report here. For example,
you quote (I'm splitting the longer lines):
# 640x480 @ 100 Hz, 53.01 kHz hsync
Modeline "640x480" 45.8 640 672 768 864 480 488 494 530
-HSync -VSync
but I've got all these:
# 640x480 @ 60 Hz, 31.5 kHz hsync
Modeline "640x480" 25.175 640 664 760 800 480 491 493 525
# 640x480 @ 72 Hz, 36.5 kHz hsync
Modeline "640x480" 31.5 640 680 720 864 480 488 491 521
# 640x480 @ 75 Hz, 37.50 kHz hsync
Modeline "640x480" 31.5 640 656 720 840 480 481 484 500
-HSync -VSync
# 640x480 @ 85 Hz, 43.27 kHz hsync
Modeline "640x400" 36 640 696 752 832 480 481 484 509
-HSync -VSync
some of which ought to be within the capabilities of your monitor.
Is it possible that you've got hold of a piece of documentation which,
while being selective for the trio's sake, was written by someone who
had a high spec. monitor and didn't consider people who were still
using an old model becuase "they wouldn't have this card". (Most
computer literature tends to be written like that.)
