I'm sorry, I was thinking (specifically) of the 8XX port that went
from broken to maintained.

It would help if you could mention some ofthe problems you are having.

Unfortunatelly my knowlege of IDE is almost 0. Maybe it has something
to do with schedulers being used?

About network, I had better results with a much slower processor than
your reported 5Mb/s (60MHz PPC in 2.6.10)
