hal hardware awarness with newer udev

[channelzero]

As of udev-126 the udevinfo tool is not longer installed, in stable hal-versions <= 0.5.11, this tool is hard coded in linux specific code. Resulting in a hal which isn't aware of the hardware in your system. Especially lshal and desktop-apps like nautilus are affected.

The hal-developers have fixed the problem within git-repo: ​http://lists.freedesktop.org/archives/hal/2008-August/012177.html

One easy but maybe not portable solution is to set a link from /sbin/udevadm to /usr/bin/udevinfo, which worked for me. Using: udev-127, dbus-1.2.4 and hal-0.5.11.

tested above changes with udev 130 (LFS 6.4) and it works lik a charm input devices are recognised, which is important for X.org 7.4 without xorg.conf

above changes are in upstream 0.5.12rc1
