I've done a diff between 2.6.25 and 2.6.26 source code of the i82975x_edac module. As you can see, there's not much difference:

Hmm, they're different. On another m/c, I've managed to find the logged info when it booted up 2.6.26:

Thanks for the pointer. I've now installed edac-utils on the offending motherboards. It seems that the motherboard is half known about:
# edac-ctl --mainboard edac-ctl: mainboard: ASUSTEK COMPUTER INC P5W DH Deluxe # edac-ctl --print-labels No dimm labels for ASUSTEK COMPUTER INC P5W DH Deluxe
dmidecode gives some memory module info:

Unfortunately not. If there's any commands you'd like me to run, then please let me know.
If you could let me know what I need to put in /etc/edac/labels.db, that would be appreciated too.
