I tried it again with a clean ext2 on top of the raid0 device and
performance improved from 25411 K/sec to 28238 K/sec (Sequential
Input; Block wise). I also made two bonnies at the same time on each
of the devices without raid 0 on clean ext2s and got 19173 K/s on each
of them. I'l try the new patches soon.

Can you point me to docs that explain this a little bit?

yes, James Manning already pointed to the *new* *improved* :) raid
patches. I hope I've time to test them this weekend.
