No, I do not have atapicam enabled. Here is my kldstat output:

Id Refs Address    Size     Name
 1   14 0xc0400000 3703a4   kernel
 2    1 0xc0771000 6ea8     linprocfs.ko
 3    2 0xc0778000 1adb8    linux.ko
 4    1 0xc0793000 2364     accf_http.ko
 5    1 0xc0796000 aa74     cpufreq.ko

 7    1 0xc4a7a000 3000     pflog.ko
 8    1 0xc4a7d000 2d000    pf.ko

I've checked my kernel configuration file and I do not have it there either.

What else should I check?
