Hard, I guess. For one you do not have all memory available to test as the kernel and many processes are using (more or less) random portions. Secondly: what would you do when you do find an error? Raising a panic is in many cases inapropriate. For example: the signal 11 (and 10 & 6) errors I am experiencing are raised by cc1 (the compiler proper) only. From the limited testing I managed to do, I got the suspicion that the errors have something to do with the motherboard and not with the SIMMs as such. Although not perfect I can live with that.
