I've rebuild kernel without any CALIBRATE_XXX options
but it still tries to calibrate clock and hangs for 15 minutes exactly
then proceedes to probe devices and boots Ok.

When I first booted this old machine its BIOS said that Date/Time in CMOS
are corrupted and asked to press F1 to enter SETUP to fix this
or press ESC to continue booting. Enterins SETUP and correcting
settings does not help and BIOS complains again that Date/Time are wrong
and does not proceed without a key is pressed on keyboard.
That's not suitable for small standalone router so I went to the store,
bought Duracell DL2032 3V battary and replaced old
Panasonic CD2032 3V battary. That satisfied BIOS POST and it no more
complains about Date/Time. But FreeBSD spends 15 minutes to calibrate clock.

Now I've put back old Panasonic CD2032 3V and hey, BIOS complains again
but FreeBSD boots normally and completes clock calibration very quickly.

I wonder, how new battery may affect clock calibration routines
and why old bad battery does not affect it that way?
