Can you also provide the line equivalent for 
 * Fujitsu LIFEBOOK E554   0x570f01        40, 14, 0c      2 hw buttons
?

Where do I find those three values mentioned in the third column? And is
that line important at all? I just did below patch as a drive-by-patch
and from looking at the source code I can't immediately spot how to get
them :-/

FWIW, it's a 2 hw buttons touchpad and I saw this in dmesg

psmouse serio2: elantech: assuming hardware version 4 (with firmware
version )
psmouse serio2: elantech: Synaptics capabilities query result 0x50,
0x12, 0x09.
psmouse serio2: elantech: Elan sample query result 01, 27, 86

Are those values from "Elan sample query result" what you are looking
for? Then the line would be:

Fujitsu LIFEBOOK E547  0x470f00        01, 27, 86      2 hw buttons

Ciao, Thorsten

Temporary got a Fujitsu Lifebook E547 into my hands and noticed 
the touchpad only works after running

echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add it to the list of Fujitsu machines that need this workaround.
