Comment 4 for bug 492729

@ZengPeng -- could you retest with the 2.6.32-7.10 lucid kernel and confirm the behaviour is still present. If so could you then try the 2.6.32 mainline kernel for me and confirm that your trackpoint is recognised there. This kernell can be found in the mainline kernel archive at the url below:

If this kernel does work could you attach dmesg output from both the 2.6.32 mainline kernel and 2.6.32-7.10 lucid kernel for comparison. Thanks!
