You probably failed to install hal.conf in /etc/dbus-1/system.d/ -
basically the system dbus-daemon has not seen the policy rules that
allow hal to connect to system bus.

BTW, I recommend using OpenEmbedded [1] or scratchbox (and a known
distribution) [2] rather than hand cross compiling, it should save you
lots of pain like this.

Thanks,
Rob
