The latest firmware is out for the Garmin 910XT. Looking at the Garmin website (which is the only way you should update your firmware) you will see that the fixes seem to be mostly with the altimeter functions.

UPDATE: This does not fix the current pace bug.

These have been problematic previously but not affected me. Other cyclists though have major issues with this.

However, talk on the forums suggests that this firmware also fixes the CURRENT PACE issue – even though it is not in the list of bugs fixed.

I’ve just updated mine and so will report back. Currently I have up to 30 secs per km pace inaccuracies.

BUG FIX: If you are unable to update your firmware then what you need to do is totally uninstall the ANT+ agent software form your PC and then re-install and pair your devices. You WILL need to turn PAIRING ON on both your watch and in the software.
