Hi Cara, Unfortunately, that sure does look and sound like a powder post beetle to me (though it's hard for me to be positive without the antennae). If the altarpiece is on open display, you might want to alert the people who clean the gallery that the frass will resemble extremely fine sawdust or even very light dirt. It is very easily mistaken for other substances. Luckily these beetles are pretty weak fliers. If you can't get the object into treatment any time soon, you could be able to partially control their movements by using a UV lure in the gallery after hours.

I don't have any photos of exit holes, but the raw wood visible on this altarpiece does have plenty of old signs of pest damage. This is a loaned object that reportedly has been treated twice with anoxia in the last year, for what type of pest activity I am not sure. (It is typically on display in a church, however, so the likelihood of re-infestation seems high in that kind of environment.) There was no frass visible below or around the altarpiece, however this object is currently installed so I wasn't able to lift it up to examine very closely.
