Yup, that's expected.  I'm not sure if usleep was planning to "fix" this
(remove the message) or if it's not possible.  I don't know what the
interaction with i2c is.

The delay is because the firmware needs to be downloaded onto the card over
the I2C bus.  If you have two tuners (like the pvr500) it's twice as long
:-P  There's no way to avoid this, at least with the current I2C
implementation.  The kernel has to block interrupts so the I2C timing is
perfect, AFAIK.
