EDID errors after Debian Squeeze upgrade


I recently performed an upgrade of my Debian Squeeze server to include the upgrades available in squeeze-backports.  After the upgrade, I noticed a lot of dmesg's like the below.  In fact, they were repeating every 10 seconds.  The cause was simple: the ancient monitor I had plugged into the server.  It was an HP monochrome monitor from probably the early 90s.
