I know what's happening here -- the system gets confused because
SYMBOL-HASH of NIL (= CDR of NIL) becomes negative if static space is
up there.  Bad things ensue.  Fixing this is probably easy.

Do any of the problems go away if you adjust the symbol-hash vop in
src/compiler/x86/cell.lisp to have
  (inst and res (lognot #x80000003))
instead of
  (inst and res (lognot #b11))
?
