 this is from crash(8)?  can you try gdb, see if it can trace
 through the trap and where it really is happening?
 
 this probably is some teardown issue, as it seems that X tries
 and then fails, and then we crash.  can you try the vesa driver
 for now, it should have a reasonably performance until we
 figure this problem out.
