Yours is 'NOUVEAU(0): Chipset: "NVIDIA NV84"', mine is 'NOUVEAU(0): Chipset:
"NVIDIA NVa5"'.

The identification from the kernel is similar but not exactly the same: yours
is "Detected an NV50 generation card (0x084200a2)", mine is "Detected an NV50
generation card (0x0a5480a2)". The BIOS version is also very different.

It could be an issue with similar effects but due to a different bug.

I am not an expert, therefore I have nothing else to add. We should wait for
developers to get back, I suppose...

Well, at least you can revert back to previous versions ! Mine has never been
working !!

> PS/2 connected, or USB?

I use an internal Touchpad from Synaptics, but external USB mouse also works
fine.

The file that you attached
(https://bugs.freedesktop.org/attachment.cgi?id=49480) also shows "(II) NV:"
and not just "(II) NOUVEAU(0):".

But, it's up to you, if you think it's pointless to try adjusting that...
