Ok,
Does writing 1 or 0 in  /sys/devices/platform/eeepc-wmi/touchpad do anything ?
The DSDT doesn't seem to provide anything do control the led, but
maybe they mixed up some bits, and this file control the led instead
of the touchpad.

Disabling the touchpad should be possible using some utility specific
to your touchpad model (synclient for synaptic touchpads).

How did you install 2.6.39 ? Because sparse-keymap should comes with it.

Thanks,
eeepc-wmi and eeepc-laptop are calling (almost) exactly the same
method for cpufv, so it's clearly a bug somewhere else. That'll be
hard to fix without hardware. What we can try is to enable acpi debug
features before writing into cpufv:

See http://www.kernel.org/doc/Documentation/acpi/debug.txt

echo 0xffffffff > /sys/module/acpi/parameters/debug_level
echo 0xffffffff > /sys/module/acpi/parameters/debug_layer

That should produce a lot of output in dmesg when doing anything
related to ACPI. You should try it with X stopped.
