Maybe the pins for those temperature inputs aren't connected and are
floating around? <shrug> Idle speculation on my part, however.

If you have a copy of i2cdump, take a look at registers 0x21, 0x24 and
0x25 a few seconds after reading the sensors via sysfs; if the values that
i2cdump shows you match what you're seeing, then there's nothing the driver
can do.  If, however, temp2,5,6 go normal after a few seconds of
waiting, then we need to increase the wait time during the temperature
sensor read a bit.
