Which chipsets on which boards?  The Nehemiah CPU is used on a couple of 
boards.

Can you try running without root and make sure that nothing is suid (you 
may lose DRI and X will probably complain a lot).  At least try running 
Matchbox without root because that would make it much more difficult for 
a rogue process to lock the whole system.  Also check if the $CFLAGS or 
$CXXFLAGS environment variables are set.
