OK I now it is a bit strange to reply my own mail but I may have found the
problem.
if this is not the true replay.
I have not patched the kernel with the new i2c header file. trying with this
insted.
SO I gees the procedure is
make patch and patch kernel new i2c module
videodevX-20010501.tgz (tar -zxvf make make install)
driver-20010316.tgz (tar -axvf make make install) (is this a 8.0.x
version?)
