looking for tslib plugin "friendlyarm-ts-input" source

onoj
system:      tiny6410_a70
touchscreen: 7" 1wire (/dev/touchscreen-1wire)
kernel:      2.6.38-FriendlyARM
tslib:       1.4
distro:      debian squeeze
--
does anyone have friendlyarm-ts-input.c ?
--

the linux and ubuntu "-s" root file systems, for example: 
- rootfs_qtopia_qt4-s-20100917.gz
                   ^^
- rootfs-ubuntu-0910-s-20100917.tar.gz for example
                    ^^
contain a tslib plugin called "friendlyarm-ts-input" that provides support
for this systems 7" 1wire touchscreen (/dev/touchscreen-1wire)

so instead of:
  module_raw input

the /etc/ts.conf file contains:
  module_raw friendlyarm-ts-input

this maps to a tslib plugin: /usr/local/lib/ts/friendlyarm-ts-input.so
(in rootfs_qtopia_qt4-s)
                     ^^
I need the source for this - i'm sure many of us do :)
friendlyarm-ts-input.c

--
copying friendlyarm-ts-input.so over works but I not comfortable using it
without the source

cheers
