Is this specific to one firmware version?
My dmesg says
[4.013727] psmouse serio1: elantech: assuming hardware version 3 (with
firmware version 0x450f01)
[4.037566] psmouse serio1: elantech: Synaptics capabilities query result

** Patch added: elantech_v7.patch
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1166442/+attachment/3742049/+files/elantech_v7.patch
** Also affects: linux (Ubuntu Precise)
Importance: Undecided
Status: New
** Also affects: linux
Verified the patch applied to the LTS quantal backport kernel. Patch
should apply cleanly to all kernels between 3.5 and 3.10, and since it
affects a broad range of Samsung laptops it may well be worth
considering for SRUs to precise and newer.

Thanks! This is the most promising lead I've gotten. A reviewer on
newegg running Arch said he fixed it just by unloading the psmouse
module, but I can't understand how that could have help unless he meant
he was going without touchpad altogether. But there is no way to comment
on reviews.
