Thanks to Benjamin's help and his neat patch which allows tempering with
quirks through sysfs, I got the device

eGalax 0eef:a001

to work. It works with the quirks

MT_QUIRK_SLOT_IS_CONTACTID | MT_QUIRK_ALWAYS_VALID ( = 18 )

so, using Benjamin's interface:

(1) Adding the device with
$ cd '/sys/modules/hid_multitouch/driver/hid:hid-multitouch'
$ echo "3 0eef a001 1" > new_id

(2) Setting the quirks with
$ echo 18 > '0003:0EEF:A001.0001/quirks'

That's it. The device works!

regards,
Cedric
