@Nicolas D.
Your alps touch pad on the E6230 is failing to complete the initialization sequence. It looks like it has the same signature as the alps touchpad on the E6430 and E6530 so the system thinks it's configured but it's not operational. Possible solutions:
1. Hardware failure and the touchpad needs to be physically replaced
2. This is a new alps model, different from the "new" one Ben Garami reverse-engineered a couple months ago for the E6430. I did the same steps for the N5110 for it's signature - very technical.
3. hack the alps dkms to glean more information about why it's failing.
The fix for (1) is to take it to a Dell dealer.
The fix for (2) is to re-trace Ben's steps to analyze the touchpad. He was mostly posting in a looong thread on the linux-input newsgroup under the title "New Alps protocol in the wild?", which can be googled.
