Ah, this is good news, I recently upgraded from Suse 8.2 (Lunux 2.4.x) 
to Suse 9.1 (Linux 2.6.4) and the latest modem_run from CVS.

The kernel module worked fine, but modem_run failed to work correctly. I 
tracked down the problem as being with the mutex handling, and applied 
the very dodgy hack at the end of my email to get myself back online... :)

The rest of my setup from Suse 8.2 seemed to work, except when pppd was 
started first time I got:

Oct  3 11:41:41 linda pppd[9077]: pppd 2.4.2 started by root, uid 0
Oct  3 11:41:41 linda pppd[9077]: ioctl(ATM_SETBACKEND): No such device

Which was solved by "modprobe pppoatm". Is there any way to make pppoatm 
get loaded automatically?

John.
