I gave up using wvdial as it seems it is not properly ported to ARM.  This post 
gives a hint of the problem:

"wvdial seems unusable on armel due to reliance on the unimplemented sysv 
ucontext API in glibc"

https://bugs.launchpad.net/ubuntu/+source/wvstreams/+bug/383978

I don't know if this was resolved.  I seem to remmber it was possible to 
compile the code by commenting out various things that turned out to be crucial 
to proper operation of the program - so divide by zero would seem to a symptom 
of this.

I don't use the TS7260, just the TS7250 and TS7550, but never got wvdial 
working.  I stuck to pppd.
