I just spent many hours installing Jessie onto a vivopc, VM42, which
seems to have this same keyboard. The driver really should be loaded on
the installer!
I'm surprised that the only place (so far) that I've found this
referenced is in this bug report over a year old now...
(I ended up installing by using the graphical installer, using the mouse
to select all the defaults, and then setting account passwords with a
rescue CD after installing, but that shouldn't be necessary at all!)
