[Bug 565543] Re: Alps touchpad detected as ImPS/2 Generic Wheel Mouse(in VAIO E series) after the kernel upgrade

[TANAKA Katsunori]

I confirmed that 2.6.32-22.36 detects my touchpad as AlpsPS/2 ALPS
GlidePoint and I see Touchpad tab in Preferences -> Mouse. Contrarily,
2.6.32-23.37 detects it as ImPS/2 Generic Wheel Mouse and I don't see
Touchpad tab.

Changelog of 2.6.32-23.37 says:
  * Revert "(pre-stable): input: ALPS - Add signature for HP Pavilion dm3
    laptops"
    - LP: #550625

diff from 2.6.32-22.33 to 2.6.32-23.37 includes:

This revert might affect PCs other than HP Pavilion dm3 as well.
