Hi Chris,
the update did not change any symptoms for me.
Booting the kernel without the option 'psmouse. proto=bare' results in the trackpad not working just as before. The only response it will produce when you touch the trackpad is (on rare occassions) it might instantly jump to a random part of the screen, it might disappear, it might result in random keyboard input. Without being touched, every 2 seconds or so, the cursor will drift 50 or so pixels to the left of the screen. I used to fix these by running 'sudo modprobe -r psmouse' and using an external mouse.
Booting the kernel with the option 'psmouse. proto=bare' makes all these symptoms go away and basic functionality of the trackpad work.
Here's the output you requested:
lansdell@juneau:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

In the process of flashing the BIOS to the latest (509) I did learn one thing: the model of my laptop (ASUS X550LA-DH51) differs from what was advertised by amazon when I purchased it (ASUS D550MA-DS01). This is strange, and was a surprise I only learnt from the trouble I had flashing the BIOS with the latter's BIOS files instead of the former's. Mainly its relevance here is that the title of my bug report lists the wrong model.
Let me know how else I can help.
Regards,
Ben
