It appears that this driver can work in non-accelerated mode without the firmware. Furthermore, it appears that in the default configuration, which is used in Debian, it *is* in non-accelerated mode and *doesn't* use the firmware. (See the USE_ACCEL define in rendition/rendition.c.) So, much like the two which Michael Daenzer mentioned, these are unused, and therefore no loss at all.
