I did run mandriva 2009.x on a PIII with 256Mb of RAM a year ago.
Hopefully upgraded to 512Mb
Yes video playback is painful on original i810 but it worked.

Yes x86_64 consumes a little more RAM.
But on the other hand it :
- leverages SS2,
- offers twice more regular registers that are twice bigger
  (and yes register pressure is a big issue on x86)
- offers twice more SSE registers
- enables to actually use the RAM between 3 and 4Gb which is not
usable on quite a lot of chipsets.
- it makes easier to use bigger disks (64bit math for adressing
sectors on big volumes is expensive on 32bit)
