Subject: CONFIG_THERM_PM72 is missing from .config from recent kernels (2.6.10, 2.6.11)

CONFIG_THERM_PM72 is required for thermal management in at least
Macs, most notably the PowerMac G5. Without it, the computer will run
its fans at the max and is very loud.

It's missing from .config in at least a few releases of recent
kernels (2.6.10, 2.6.11).

Does anyone know why?

Did you enable/select it?
It's not on by default (in 2.6.11-rc2).

First you need to enable this one:
config I2C_KEYWEST
tristate "Powermac Keywest I2C interface"
depends on I2C && PPC_PMAC

and then this one:
config THERM_PM72
tristate "Support for thermal management on PowerMac G5"
depends on I2C && I2C_KEYWEST && PPC_PMAC64

Thanks.

This is probably something for the config program designers, but
options like these shouldn't never be hidden. They should always be
available. If their prerequisites are not met, then it should reject
change and throw up an explanation message, namely, the above.
