from what i gathered, race car drivers first started using drilled rotors to dissipate heat away from the surface and allow cooling. but then they realized that drilling or not drilling them properly causes the rotors to crack easily...espeicially in the high stress factors that the rotor is subjected to during racing. so now most race car drivers use slotted rotors because they can withstand the heavy braking longer than cross-drilled rotors. but the above is only true for race applications
"drilled" rotors are not infact drilled, but rather formed that way (which is why the real ones don't crack). and none of this was to dissipate heat, but rather to get rid of gasses which were caused by older brake setups...
