Aye, but softmodem drivers will be run on non-RTLinux systems. Because it's simply for users who want to use their winmodems. And it would like a bounded latency please during 99.9% of all seconds (hard RT not strictly required). None of this "I started netscape and the latencies suddenly jumped 100 times".
