    Sure I can use gstat (it actually displays statistics for acd0 and fd0) but
I consider current behaviour regarding devstat(9) as broken. Note that if I
configure atapicam into the kernel, devstat sees ad0, cd0 and pass0, but 
doesn't see acd0 and fd0. What's the problem with those devices? What
makes especially cd0 "better" than acd0?!
