Without the sleep, switching is as fast as before.
It is weird tho. Could you try adding a printk or something to figure out how much this is called during a typical swich ? It will seriously spam your console though ... I would expect only 5 or 6 calls during a normal switch (since the PLL value shouldn't change for a flat panel), that is no more than maybe 50ms, while it seems you are having a much bigger delay.
