Thanks for your precisions, I think you talk about "optical drives" ejection ?
First of all about optical drives, but udisks provides Eject method for general drive class. I'm not sure what effect it will take if it would be called for e.g usb-stick.
You're right, I think that 99% of the time, the connected user can eject them with eject command ...
  What about the mount feature ? Can't udisks(2) be used for that purpose, instead of pmount ? We do not have a "-DWITH_PMOUNT" option yet, but distributions are more likely to provide udisks than pmount ...
 I've told about this in the first answer on the thread. For now it won't be introduced before 14.1 because it will require API changes.
That's what I'm afraid of.
From what you know, can Upower be built on any (old) distribution, or does it require recent kernel/libraries/etc .. ?

sorry, dunno... 
If I remember what was said before, -DWITH_HAL=ON is incompatible with -DWITH_TDEHWLIBRARY=ON .
Does that mean that, if I build with HAL and without hwlibrary, I will automatically lose upower, udisks and pmount support too ? I guess I will also need to stick with kpowersave and knetworkmanager8, instead of tdepowersave and tdepowermanager.
yes, it's so, but I can say only for tdebase...
