Good news for you: the TVGA9440 driver is currently in beta-test for
XFree86/tm.

Seems that there are not enough color cells for highlighting.
Try running it with a StaticColor visual instead of PseudoColor. This
would mean that the server knows only about its predefined 16 colors,
and the applications cannot use the palette registers. All colors
will be approximated then. Perhaps this looks better.
This is the appropriate section from XF86Config for my notebook:
# The 16-colour VGA server
Section "Screen"
Driver "vga16"
Device "Generic VGA"
Monitor "LCD"
Subsection "Display"
Visual "StaticGray"
Modes "640x480"
ViewPort 0 0
EndSubsection
EndSection
You should replace the "StaticGray" by "StaticColor", and use whatever
Device and Monitor strings are appropriate for you. Then again,
perhaps "StaticGray" might also be an option for you?
Err, StaticGray was known to be broken in XFree86 3.1.1's VGA16
server, here's the patch:
