I just committed the real fix in r330131.  Basically any copies of
ubldr built between rr329190 and rr330131 won't load modules properly,
with the symptom being a lockup or kernel panic early in boot.  If you
load no modules in loader, everything should be fine; loading modules
after the kernel has started works in all versions.
