Should not it be actually "evdev" always? As evdev is really the only driver
that would work?

Does not work; results in empty string with commas, something like ",,"
and X loops taking almost all CPU time.

Can I really set anything besides evdev, given, that ...

... HAL sets above options - so far - only for evdev devices?

And how I resurrect my 3rd button emulation on notebook with 2 buttons?

Anyway here is what I tried as FDI:

{pts/0}% cat /etc/hal/fdi/policy/x11-keyboard.fdi
<?xml version="1.0" encoding="UTF-8"?>

<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="input.keyboard">
      <merge key="input.xkb.rules" type="string">xorg</merge>
      <merge key="input.xkb.layout" type="string">gb,ru(winkeys)</merge>
      <merge key="input.xkb.options" type="strlist">grp:menu_toggle</merge>
      <append key="input.xkb.options" type="strlist">grp_led:scroll</append>
    </match>
  </device>
</deviceinfo>

but due to xkb.options misbehaviour I stopped further experiments.
