Are you using synaptics X driver? It can be tweaked to adjust
sensitivity and lots of other things.

Have you tried synclient utility? It temporarily disables the touchpad
when you start typing and re-enables it when you done.

Unforch, my questions along those lines have been treated as the ravings of
a lunatic and ignored. The bios has no place to disable it, dumbest bios
I've seen in quite a while, and it has been updated in the last 3 months.

I don't *think* I'm a lunatic, but I'm equally sure that the synaptics is a
pain in the ass and should be capable of being totally disabled somehow,
hopefully short of opening the lappy up and unplugging or cutting every
lead to it until such time as it can be made to behave instead of
responding to every thumb waved 1/2 to 3/4" above it. I've gotten hand
cramps trying to hold my thumbs far enough away from that abomination to
stop such goings on.

So count this as a vote FOR doing something about the synaptics touchpad

There are ways to disable it:

echo -n "manual" > /sys/bus/serio/devices/serioX/bind_mode
echo -n "none" > /sys/bus/serio/devices/serioXdrvctl

This should disable it completely.
