Comment:

 There is additional timing information gleaned from SHC00500826 tonight.
 The VX855 appears to be making the LPC requests properly for the SIP data,
 followed by initial boot code.  It then quickly stops requesting data.

 Scope traces describing this are available at:
 http://dev.laptop.org/~wad/xo1.5_boot/10314.html

 I will hook up the DLA to the LPC bus tmw., but have no way of easily
 accessing the FSB due to it's internal routing and a lack of test pads.
