I'm still trying to narrow this down a bit...

It seems that if I rebuild a kernel from sources as of 2009-11-09 17:00 
UTC, the system boots.  Yet a kernel from sources updated to just one 
hour later, at 18:00 UTC, fails.  The only commit during that interval 
was the update of sys/sys/param.h from 5.99.21 to 5.99.22 - no other 
source files updated!

The target system has both 5.99.21 and 5.99.22 modules in /stand/amd64/ 
and the same 5.99.22 modules work on all my other Intel and AMD CPUs. 
The modules are built from yesterday's (2009-12-17) sources.

I guess I can do a binary search to figure out when the modules broke...

What module(s) would be loaded at such an early part of the system boot?
