What are the downsides of ASMP?
Only explicitely AMP aware applications can take advantage of the additional cores. All other software can use teh main core only. On SMP the OS schedules all tasks/threads more or less well balanced to all available cores.
And that would be more than fine for us I think. Old legacy programs run happily with single core and more cpu hungry programs are still in development so they could be adapted. I don't think full SMP would give that much more in comparison to AMP in our case. Getting AMP would be big enough step here and probably possible before breaking everything :) Getting mplayer, reggae and similar stuff to use second cpu would be a good start...
