The bios on the board is a PMC 49FL004t-33jce.  Found a data sheet for 
that, and it does use the LPC.   I'm looking at the SST parts right now.

Looks like this is shown with flash rom?  Guess it's time to fire up svn 
  and grab some code.   This stuff has come a long way since the 27cxxx 
chips. :)
