Alps touchpad and point stick not recognized on Latitude E6510

+++ This bug was initially created as a clone of Bug #473894 +++
I have reported this bug upstream:
Description of problem:
My DualPoint trackball & touchpad work, but they are not recognized as Alps (they are recognized as "PS/2 Generic"). Without recognition, scrolling does not work, but tapping does.
I checked kernel source 'drivers/input/mouse/alps.c' & have confirmed that it is missing my device's bus/vendor/product ID triplet:
I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
H: Handlers=mouse2 event7
B: KEY=70000 0 0 0 0
I compiled a custom kernel to include my device ID triplet with byte mask "0xf8, 0xf8" & flags "ALPS_PASS | ALPS_DUALPOINT", but that didn't enable recognition. I'll try other options & update this ticket & upstream ticket upon success.
The trackball has 3 buttons; the touchpad has 2 buttons with vertical &
horizontal scroll indicators.

The patch from this post: https://bugzilla.kernel.org/show_bug.cgi?id=14660#c32
seems to be semi-working based on this post https://bugzilla.redhat.com/show_bug.cgi?id=590880#c19 from the E6410 touchpad bug page.
There is also another patch at: https://patchwork.kernel.org/patch/118834/ that some success has been reported with.
Hope some progress can be made on this before I receive my E6510.
