No, that's a different story.  In fact, the patch to cxacru.c I posted
the other day (still not commented by anyone, hint) was applied here
too, so the ATM device was created only when the modem was fully
initialised.  At that time it's definitely usable.

No, you don't want the ATM device to disappear if someone pulls out the
phone line jack.  That's what atm_dev->signal is for.

The problem I'm seeing is in pppd: if it fails to establish a
connection, it should either retry or exit with a failure code.  Instead
it's going to sleep forever, and that IMO is a bug.
