[HP EliteBook Folio 9470m Notebook PC] Touchpad not recognized after upgrade 13.10->14.04

[Claus Lensbøl]

I'm not perfectly sure the problem lies here, but after reading several arch linux bug repports that points towards a kernel issue, I'm reporting it here.

After upgrading my HP Folio 9470m from 13.10 to 14.04 I no longer have a working touchpad.
As far as I can tell it gets recognized as a generic mouse, from xinput:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Sleep Button id=8 [slave keyboard (3)]
    ↳ HP HD Webcam [Fixed] id=9 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
    ↳ HP WMI hotkeys id=12 [slave keyboard (3)]

From dmesg | grep -i touch:
[ 12.334048] psmouse serio1: alps: Unknown ALPS touchpad: E7=10 00 64, EC=10 00 64

It should be pointed out that i ran a couple of days in prerelease (from the 12th iirc) with no problems. It is only after the official release I have had this issue.

If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.
