Put your driver into the kernel. I'd suggest an interface similar to the current soundcard interface, plus ioctl's to handle phone line specifics, like hangup etc.
The realtime guarantees should be ok when using what the kernel already provides (mlock, sched_setscheduler), as long as it can control when exactly a waveform gets transmitted. It can do this by sending the right amount of zero samples to the soundcard aka modem :)
