Synaptics Touchpad problem 22.214.171.124
A while ago, I compiled my own custom kernel based on the 126.96.36.199 vanilla, which all went fine. When I started up my Ubuntu 7.1 system with the new kernel (NEC Versa P520 laptop), my synaptics touchpad did not work anymore. With the standard 2.6.22-16 kernel it works fine! I don't believe that there is a problem with the supplied driver or even with the kernel. I guess there is a problem with Xorg or Ubuntu, but I have no idea what it is.
Here's my dmesg (shortened):
And of course my /proc/bus/input/devices:
PNP: PS/2 Controller [PNP0303:KBC0] at 0x60,0x64 irq 1
PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp
serio: i8042 KBD port at 0x60,0x64 irq 1
mice: PS/2 mouse device common for all mice
which shows that it's not found (in the new system). My Xorg.0.log tells me that

but in my kernel evdev is built in, so that's not missing. Making it a module does not resolve the problem.
Synaptics Touchpad no synaptics event device found (checked 15 nodes)
Query no Synaptics: 6003C8
[...] no touchpad detected and no repeater device
unable to query/initialize Synaptics hardware
Somehow there are no /dev/input/event* entries, which are normally found according to my working Xorg log: "Synaptics Touchpad auto-dev sets device to /dev/input/event*" etc.
I don't know why my system does not recognize my touchpad with the new kernel. Any thoughts? I have tried using a linux-source (downloaded with aptitude) but that one has the same problem, even if I use my old configuration.
Actually, I had the same problem with the live cd of 8.1, which is why I am still with 7.1.
Anyone have a solution or idea what's wrong/missing? I have asked the question on the ubuntu forums, but no one there has an idea. I hoped some kernel guys here might know what I am missing... Is there a module that controls /dev/input/mouse and I am not aware of it?!
The following, which was suggested to me, did not work:
Neither does this.
sudo dpkg-reconfigure xserver-xorg
Any help much appreciated.
