A real-time (-rt) kernel is available and has been for at least a few 
releases.  PREEMPT (which Lennart says would help) was enabled once upon a 
time, but I think it was disabled due to high laptop battery usage or 
something like that.  After that email from Lennart, discussion about it came 
up again, but it was way too late in Jaunty's cycle to be changed by that 

But uh yeah...I do intend to at least bring it up at UDS and see what the 
kernel team says.
