It worked.

I cvs'ed the current sources (4.99.26, not recommended for anything but 
test PCs) and compiled them through build.sh with the options you 
specified (multiproc w/ mpacpi instead of mpbios).

Here is the configuration file for the curious (and especially for those 
who have a Dell Latitude D820):

Here is the customized NetBSD 32bit boot binary for the experimental 
(put in as /netbsd):

Thank you kindly for your help, I look forward contributing to the 
NetBSD project.
