Is there any way of Filtering out messages from OS X system log?
if you just wish to hide the error messages that are cluttering up the console log, for easier readability, then this can easily be accomplished by selecting any one of the offending event messages, then click 'Ignore Sender' on the Console toolbar; those messages will then be hidden from view. the event messages are still generated, until you fix the obsolete driver issue, but you won't see them in the Console. see more info HERE and HERE.
