Which lists firmware version 61ET20WW, which according to:
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67008

is a *VERY* outdated BIOS.

And it looks like there are two firmware versions (61* and 63*). And many
releases. If the BIOS update program also upgrades the EC, it can very well
fix i8042-related problems, since it is usually emulated by EC firmware.

Doesn't look like a quirk you can tie to just model type. And if you do,
the three last letters usually doesn't mean much on any Lenovo or IBM box.
The first four are the main model type.
