if you open up a terminal window, and type in modprobe hid-multitouch the 
touchscreen will start working correctly. The module just isnt being "detected" 
like it should. as an fyi to the developers... the B121 and the ep121 are 
identical hardware wise, and i can verify that the touchscreen on the ep121 
works correctly "out of the box."

When running the modprobe I get a Operation not permitted error. Running SU 
from the terminal window gives me Permission denied and superuser logs it as a 
deny. Anyway around this?

Nevermind... You must install Android x86 in read only mode and not read/write.

I have it installed as read/write and had no trouble running the command. Maybe 
SU was set to deny terminal by mistake, as deny was selected by mistake when SU 
was asking whether or not to grant terminal SU permissions ... ? Just a 
thought... but glad you got it to work.

Anyone know how to automatically run the modprobe command at startup?

Add the following to the init.sh file in the etc folder or just replace your 
file with the one I attached. You'll have to install something like root 
explorer and mount as read/write in order to replace the file or modify the 
file.

# Activate Touch Screen
modprobe hid-multitouch
