The bugs are probably closely related and may even have identical causes in the end, but the original symptoms are very different. For this bug there was a patch to xorg-server that worked for most people - but apparently not all.
But until it is established that they *do* have identical causes, I'd vote for keeping the bug separate.
@Martin Pool: Are you sure you experience *this* bug? The symtoms of this bug are described for example here: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/194214/comments/103 (if you say it happens "a few times an hour", I don't think you keep restarting your X-Server every couple of minutes to get out of key repeat loops?), however the symptoms of bug 124406 are intermittent key repeats (and probably key losses) that stop *by themselves* after a few repeats, and are much more visible for normal keys instead of modifier keys.
