Apparent regression in current version: Synaptics trackpad on HP -- right click, click and drag not working

HP DM1 3101EA
Ubuntu Oneiric beta 1, all updates as of 21 Sept.

By default (and with changes in the system settings/mouse and touchpad option):
Trackpad multi-touch (two finger scroll, for example) works
Trackpad tap to click works
Right click - does not work at all
Click and drag only works within the space of the 'left button' area of the trackpad - doesn't work overall.

Problem is resolved by installing the deb (dpkg - i ) at
http://www.mdl4.com/2011/07/fix-your-hp-mini-mouse-in-ubuntu-11-04/
and restarting the X server (ctrl-alt-backspace)

Subsequent updates will install the 'broken' xserver-xorg-input-synaptics release unless pinned.

I'm not technical enough to actually figure the difference, but it transforms the PC from virtually unusable to perfectly normal.

If the regression 'fault' in the detection/config of the synaptics trackpad could be incorporated into the next update to the the package, that would be great.
