Und der Vollständigkeit halber hier auch die Release Notes für die Firmware 1.1.1 der EOS 5D:

The following fixes and improvements have been incorporated:

It now supports high-capacity CF cards.
Previously, when using an 8GB CF card or greater (e.g.,12GB, 16GB), even after initializing the card in the camera, the CF card capacity could not correctly be detected.
This phenomenon has been fixed so that the camera will correctly recognize high-capacity CF cards.
It allows the latest lens names to be recorded in the Exif information of images taken.
The lens IDs of lenses released after EOS5D are not in the camera; so these lens names could not be recorded in the Exif information of images. The lens IDs for the follwing new lenses are now included, so that the correct lens names will be recorded in the Exif information of images.
