Ubuntu mainline 3.(1|2|3).* kernel with tp-smapi-dkms installed freeze on lightdm logon screen in Linux Mint 12

[petermolnar]

After a fresh install of Linux Mint 12 (Lisa) I've experinced the following: ubuntu mainline kernel version 3.3 [http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-precise/] (also tested 3.2.9) for Precise was installed successfully, along with dkms packages, including tp-smapi-dkms, a package for ThinkPad computers hardware diagnostic information.

The bug: the system boots but on lighdm logon screen I get no response for trackpoint or touchpad device. If I want to access console with ALT+FX keys, the system freeze, no response from that point to any keystroke. Same freeze after password is correctly entered: lightdm disappears until a point but nothing - including the wallpaper - show up.
The system needs hard reboot when it reaches one of the freeze points.

I was unable to detect anything reasonable out of dmesg or syslog, but after lots of clean install testings I'm truly sure the tp-smapi-dkms package is the cause.

System details:
HW: ThinkPad T400, P8700, 4GB RAM , Intel X4500HD no special hardware
SW: Mint 12 Julia, no ppa, no hacks, solely new kernel + tp-smapi-dkms

Added modules in /etc/modules:
tp_smapi
thinkpad_ec

Please tell me what kind of information I can get to help solving this.
