True,  but they run that with a fairly low frequency crystal,  same one
that's used in most of the watches out there,  32.768 KHz.  The lower the
frequency,  the less CMOS draws for power.  I haven't measured the current
draw for one of those yet,  but don't think it's likely to be that much
more.

That doesn't sound like it'd do much.  Figure 0.6V per diode,  the +5 would
be dropped to 3.2,  which sure isn't enough to charge a 3.6V nicad...
