Here's what I'm doing, maybe it helps others:

The other Fn-FX keys work for me (except Fn-F1 but I forgot what I
did/not try about it).

In the above file the three volume-stanzas are probably useless; the
volume-key-events show up for me only after reinstalling
hotkey-setup, maybe there's another possibility, too.

Oh, and as per #504643 I've diverted "away"
/usr/share/hal/fdi/information/10freedesktop/30-keymap-module-thinkpad-acpi.fdi
before.

While we're here that's how I got back the scrolling ability for the
trackpoint (found somewhere on the intarwebs):

#v+

gregoa at nerys:~$ cat /etc/hal/fdi/policy/mouse-wheel.fdi 
<match key="info.product" string="TPPS/2 IBM TrackPoint">
 <merge key="input.x11_options.EmulateWheel" type="string">true</merge>
 <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
 <merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
 <merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
 <merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
 <merge key="input.x11_options.EmulateWheelTimeout" type="string">200</merge>
</match>

I'm using xbindkeys at the moment, but something that's independent
from X and a specific user would indeed be nice. Unfortunately I
haven't found out yet if and how HAL can call events on keypresses
...
