  I believe the most common problem is the situation you are
describing: hald not ready by the time the X Server is loading,
usually due to some timing issue, and by like less then one
second.

  Maybe you could use 150ms in config/hal.c:connect_hook(), and
use like 2-4 seconds if it the first "timer" failed.

  Or maybe Daniel or Peter will implement what they commented
some days ago, that is listen for a dbus message that tells when
hald is ready and accepting connections? (I don't know about
dbus internals, and did not know dbus had that feature...)
