Subject: Tried to test agrsm-20080203.tar.gz in computer with 11c11040 modem chipset

I know this is kind of against the rules, but in another attempt to
get a working driver other than the redflag kernel,

I am tempted/have been tempted to try the AGERE code

 http://linmodems.technion.ac.il/packages/ltmodem/sv92/agrsm-20080203.tar.gz

The above code compiles and is very similar to the one provided in the
link by Frank

I see many things simiilar and many differences as well.  The second
one agrsm/ here creates the modules and places them in
/lib/modules/`uname -r`/extra/ while the first one, the 11c11040 one
places them in /lib/modules/`uname -r`/kernel/chars/.  The bad thing
is that the final step does not succeed :(
make install fails in both cases.

I tried the agrsm-20080203 just to see what I was going to get and all
seemed to be fine, the code compiles, I modprobed agrmodem, and
agrserial and then wvdialconf /etc/wvdial.conf did  not find the
modem.  I typed dmesg and I got

They are similar and they are also very different..  This is just an
observation and do not expect responses back.

This is what I do not understand.  Permission denied?  I am running as
root.  :(
