That's exactly what my friend did - ground away *carefully* with a dremel
until it was exposed.
Jeff (Technoid) on this list mentioned in the Sun NVRAM thread that he'd
done this successfully...maybe he's got some practical advice for you.
Cheers,

Hi,
Heard of few getting into theirs to hook into a new battery when
the old battery expired.
Drilled short depth in 3 places hoping to find cavity within and
didn't find it. It is completely filled with epoxy to the brim. How
did one manage to expose theirs to get at the battery itself?
I seem to remember that these devices consist of a norml IC package
(containing the silicon die) with connections on top (as well as the
usual pins along the sides to go into the PCB) for the battery and crystal
(?). The latter parts are potted in epoxy on top of the normal package.
I am told (although I've never tried this) that if you carefuly cut/grind
away at the top of the device with (say) a Dremel tool, you can expose
the connections without damaging any of the parts. Then disconnect the
old battery and wire up a new one.
As I said I've not tried this, and you'll probably ruin the first few
devices you look at, but it might be a starting point.
