The following code will enable the interrupts:

outp(0x70, 0x0B);

outp(0x71, inp(0x71

The above is from http://www.geocities.com/SiliconValley/2151/cmos.html found using http://google.com searching on outp(0x70,i); Second link first was in German.

Cheers,

PS I did the search 'cause I was curious -I was think something hexideciamal
