This patch was redone against linux-2.6.22-rc5-git8 (as requested by Mark M. Hoffman in the "kernel TODO" post).

This patch is improved comparing to previous one: 
 * it allows selection of ADM1022 working mode (THMC50 or
additional remote temperature)
 * adds doc file 
 * stops the fan with pwm1 setting to 0
 * removes interrupt mask and status files from sysfs.

Regards,
Krzysztof
