Possibly a bad data-line to NVRAM or within the NVRAM module.  I -think-
the NVRAM on a sun4m/sun4u-era Sun is accessed serially, so it'd
most-likely be that the NVRAM module itself is just bad.

Hm, but that argues against it, since the battery and NVRAM are all in
the same component.  Do any of the traces near that socket look damaged?
