Has anyone tried running a TE405P or similar under Linux 2.6 with the 
realtime preemption patch added? That code is not ready for production use 
yet, but it would be interesting to know if the frame underruns are 
eleminated. From the number that have been reported it seems like it could 
do the trich with quite a wide margin.
