no sensor module

["T. Horsnell" <tsh@xxxxxxxxxxxxxxxxx>]

Somewhere between kernel 2.6.11 and 2.6.16 the core sensor module
became no longer part of the standard configuration:

[root@lg5 ~]# ls -1 /boot/config*
/boot/config-2.6.11-1.1369_FC4
/boot/config-2.6.11-1.1369_FC4smp
/boot/config-2.6.16-1.2069_FC4
/boot/config-2.6.16-1.2069_FC4smp

[root@lg5 ~]# grep SENSOR= /boot/config*
/boot/config-2.6.11-1.1369_FC4:CONFIG_I2C_SENSOR=m
/boot/config-2.6.11-1.1369_FC4smp:CONFIG_I2C_SENSOR=m

Is this deliberate?
Do I have to rebuild the kernel to get this back?

Thanks,
Terry.
