After using those alsa modules the modem is hung even if one removes modules and
install alsa-0.9.0rc5. On the contrary, after a software suspension (which
includes power off) and reinsertion of alsa-0.9.0rc5 modules, the modem works
and /var/log/messages gives:

Those error messages are curious but only the last one (kernel: 0000006.561:
DevMgr_StartCallingTone - Fax element doesn't exist) seems critical.

Any hint ?
