Well, since I'm getting frames lost even in the test case of 
cp /dev/video /dev/null
which has plenty of datarate...

I don't think the speed at which /dev/null sinking the data is
cosing me the problem. At most memcp_tofs call in /dev/video read
method. But what is the performance of memcp_tofs - tens of MB/sec I
hope.
