I just got the 24-105 last week and so far it's been very nice. I use it on a tripod when I'm doing portraits and such and I'm wondering about the IS. In my 300 f2.8's instructions it specifically says to shut off the IS when using that lens on a tripod. But the 24-105's instructions are more vague. It mentions shutting the IS off to conserve battery power in the camera, but it doesn't suggest that IS will actually hurt image stabilization when using a tripod; as the 300's instructions clearly state.

The 24-105 is using a newer type of IS than the 300's, so things are likely to have changed. In any case I'd like to know what kind of real-world results other 24-105 users have experienced with IS and a tripod.

I always turn it off, although I have tried it with it switched on, and the results looked OK.
I can't remember what the leaflet that came with it said (if indeed it did say anything)

Best thing is to just try it yourself...

I just make it a habit to always turn IS off when using a tripod. But you're right...the manual is a bit vague (with the exception of 'Bulb' exposures). My 100-400L manual clearly states to turn it off on a tripod, then again that lens uses the older version of IS. Since the 24-105 manual doesn't specifically mention turning it off, my guess would be that its okay for short exposures on a tripod. Either way, my habit is to turn it off on a tripod.

I'd recommend you turn it off, especially on long shutter speeds in low light. I took a couple of 15sec shots of waterfalls with IS turned on and off and found that the image was better with IS turned off.
