/lib/modules/`uname -r`/kernel/char/
was the location used under 2.4.n kernels
The Agere maintainer didn't bother to update to the 2.6.n installation
recommendation, the usage of /lib/modules/`uname -r`/extra/
Alexei does follow this 2.6. n module placement recommendation in his
agrsm derivative, which we are using.
Functionally it doesn't matter, as all modules under
/lib/modules/`uname -r`/ are properly located during the bootup
# depmod -a
which calculates the interdepdencies between the modules.
The sole issue of importance is to have competent drivers
The bootup scripts in the Agere packages are not essential,
One can always manually do:
# modprobe agrmodem
# modprobe agrserial
