odd radeondrmkms messages: edid checksum failure

[matthew green <mrg%eterna.com.au@localhost>]

i see this very occasionally on a radeon 4500 kernel messages:

DRM error in drm_edid_block_valid: EDID checksum is invalid, remainder is 208
drm kern error: Raw EDID:

it doesn't seem to affect anything, but it's odd, so i'm reporting it here.
