I have setup software raid with 2.4.  I believe this are plenty of
step-by-steps out there on this topic.  Check google or tldp.org.

If you have any specific questions I will help out the best I can.

With 4 drives I would suggest RAID 5 or 0+1.  Depending on the processor
specs RAID 5 may create a significant amount of CPU overhead.  I would
avoid RAID 1 (Striping) since the failure of one drive would result in
the loss of your entire set.  I would also put all 4 drives on a
different channel if possible to maximize throughput (we are talking
IDE...aren't we?)
