 From man on the machine as installed by SL6x:

EDAC-CTL(8)                   EDAC admin utility 
EDAC-CTL(8)

NAME
        edac-ctl - EDAC admin utility
[snip]
  --load Load EDAC drivers.

end man.

[root@ahprc4 ykarant]# edac-ctl --status
edac-ctl: drivers not loaded.
[root@ahprc4 ykarant]# edac-ctl --load
Unknown option: load
Usage: edac-ctl [OPTIONS...]
  --quiet            Quiet operation.
  --mainboard        Print mainboard vendor and model for this hardware.
  --status           Print status of EDAC drivers.
  --print-labels     Print Motherboard DIMM labels to stdout.
  --register-labels  Load Motherboard DIMM labels into EDAC driver.
  --delay=N          Delay N seconds before writing DIMM labels.
  --labeldb=DB       Load label database from file DB.
  --help             This help message.

Thus, the --load switch documented in man is an unknown option.  What 
have we incorrectly done?
