This could be useful, but two of the three questions above need to be answered first :)

improves RAID-1 read performance by "balancing" reads across all available 
partitions (like RAID-0 striping).

I took a look at the patches and they're only for 2.2 Kernels

And now?

Then forget about this. It's possibly already in the current 2.4
kernel series. I have looked at Neil Browns page, he does a lot
of RAID work, and found nothing mentioned about this patch there.

http://cgi.cse.unsw.edu.au/~neilb/patches/linux/

Otherwise I can only suggest to look into the SuSE Kernel patches
if there's anything interesting in this area:
