All in all, I would recommend leaving Debian behind, and grabbing a copy of openSUSE 11.0.
Which I might add provides a very nice experience at least on my Pegasos (haven't tried it on the EFIKA yet) :)
It leaves a little to be desired on Efika - mainly because there is limited memory, the disk is not DMA-capable (this means, swapping takes CPU time, and happens a lot). Boot time is also rather long. But this is true of every Linux distribution on these boards, it just so happens that SuSE is one of those that has a LOT of functionality, so there is more to turn off.
However picking Xfce and disabling a lot of unneeded services really does work to improve system response. We are doing tests this week on this.
The two things I really do think need solving are implementing the PIO-DMA support into libata (Tim Yamin's recent patch for UDMA support, we are testing and have found some "issues" with, in that it doesn't speed anything up or lessen CPU usage.. but that is probably because of a SuSE kernel patch that is totally FUBAR) and something really silly; being able to dedicate 32MB of my Radeon's memory to swap space while still using the Radeon for graphics. Swapping to PCI memory is not as fast as even swapping to disk but at least the PCI controller does DMA, and therefore it does not soak up CPU time.
