Normally Linux doesn't care > about SPD. The Linux kernel doesn't care, but user-space may. As a matter of fact, there is a script out there (decode-dimms, in the i2c-tools package) decoding the SPD data and presenting it to the user.

The kernel code should instantiate one spd device per memory module (assuming they are all reachable.) Obviously this can't be done in a static way. -- Jean Delvare
