If it is needed only to answer "does my keyboard work", maybe you could 
store an error count in the driver, or put it to the event layer. 
Coupled with a way to retrieve the value (ioctl+evtest,proc,sys,etc), 
the user can get the information they need, but only when they actually 
want it.

The networking subsystem seems to store a lot of its error conditions in 
proc-accessible counters rather than printing a warning.  Thus there is 
precedent for avoiding dmesg spam in this way.
