+  782d and 783s datasheets differ on which is pwm1 and which is pwm2.

+  782d and 783s pin is programmable for fan3 input or pwm2 output;
+       defaults to fan3 input.
+       no control in driver so pwm2 doesn't work.

+  782d has pwm1-2 for isa, pwm1-4 for i2c. (pwm3-4 share pins with
+       the isa pins)
