May be way out, but if the caps are part of a identfiable circuit using
a particular IC chip, you may find the component values in the application
note 'example circuit' for that chip?

I actually had that idea and posted above under "help guessing value of
ceramic cap".. The caps are directly connected to the GM1212 IC and I think
from the data sheet that they have to be between 2pf and 9pf..
