Ok, I have to admit to lying; I only managed to go down to 5.8 ms  
(128/44100/2).
But, then again, I'm running a generic vendor kernel (2.6.25.11) on a  
seven years old CPU. I'd imagine a modern CPU being able to go lower,  
so my question remains:
Has anyone with a modern PC tried to go low-latency with a non-patched kernel?
