[Bug 641406] [NEW] Alps Glidepoint Touchpad Not Detected after Kernel Update

[Myk Robinson]

Public bug reported:

Binary package hint: linux-image-2.6.35-22-generic

Kernel regression, working on a Sony Vaio VPCEB24FX laptop. Touchpad
works fine from live cd, however, if you run updates during
installation, the touchpad no longer works. Reinstalled without running
updates, and the touchpad worked fine until the kernel was upgraded.
Running any variant of 2.6.35-22 (generic or PAE) resulted in a loss of
touchpad function. Booting from the previous kernel in GRUB allowed the
touchpad to work again.
