You're right! I didn't expect this error message to come from the
init.d script.

I commented out the following checks:

  * -d /proc/sys/fs/inotify
  * -d /sys/kernel (doesn't exist either)

Then hal starts.

Unfortunately it doesn't change anything with regards to X.

I moved away my xorg.conf, restarted dbus and then gdm, but neither
mouse nor keyboard are working.

The following appears again in the logfile:

| (II) Cannot locate a core pointer device.
| (II) Cannot locate a core keyboard device.
| (II) The server relies on HAL to provide the list of input devices.
|         If no devices become available, reconfigure HAL or disable
|	  AllowEmptyInput.

Keyboard is back as before if I create an xorg.conf just consisting
of:

| Section "ServerFlags"
|         Option "AllowEmptyInput" "no"
| EndSection

Also the xorg.conf which was working with 7.3 plus these lines didn't
get the mouse working. I also changed the device from /dev/sysmouse to
/dev/ums0, but this didn't help either.

Plugging it out an in while X was running didn't help either. dmesg
says:

| ums0: at uhub1 port 2 (addr 2) disconnected
| ums0: detached
| ums0: <Logitech USB Trackball, class 0/0, rev 1.10/14.00, addr 2> on
| uhub1
| ums0: 5 buttons.

/var/log/syslog only knows:

| Jun 10 16:19:19 metisse kernel: ums0: <Logitech USB Trackball, class 0/0, rev 1.10/14.00, addr 2> on uhub1

These log entries look fine to me. It seem to have found the mouse.
But the cursor just doesn't move.

If I use the minimal xorg.conf with only AllowEmptyInput or none, I
only get the following in Xorg.0.log:

| # egrep -i 'input|mouse|usb|usm|hal' /var/log/Xorg.0.log
|  X.Org XInput driver : 4.0
| (II) The server relies on HAL to provide the list of input devices.

| (II) intel(0): SDVOB: 1 input channel
| (II) intel(0): Digital Display Input
| (==) intel(0): Silken mouse enabled
| (II) Initializing built-in extension XInputExtension

Any further ideas what else could have gone wrong? Any ideas in which
logfiles to look into except dmesg, /var/log/Xorg.0.log, and
/var/log/syslog?
