It happened too with apm blanking disabled and only screen blanking without apm blanking occuring. Preventing screen blanking completely by issuing echo -e "\033[9;0]" prevented the freeze from happening so I do believe it's not the apm blanking code but the general console blanking code where the problem occurs (no X, no fb, plain 80x25).
