This was mostly (and a bit costly) pilot error.  Patch 116698-03's README says:

NOTE 3: DIMMs Support
          OBP 4.9.4 is only compatible with DIMMs using SPD version 0.0.
          If you wish to install DIMMs with SPD version 1.x, you must first
          upgrade your OBP to 4.9.5 or higher, then install the DIMMs.
          If you do not upgrade your OBP prior to installing these DIMMs, OBP
          will beep 3 times and power off. 
While this note could've been a littler clearer and said "OBP 4.9.4 *AND 
GREATER* is only compatible with..." I shouldn't have rushed into installing the 
patch without thinking about this note.  I *did* read it, but saw the old, old 
version number there (the patch installs OBP 4.16.4) and went on.

The DIMM's had to be replaced with new ones that are compatible. 

BTW, the Blade 1500 beep codes are in its hardware handbook at
