I'm interested in RAID 0 b/c I want drive speed, not drive
reliability.  I've got a full-tower ATX case which runs amazingly cool
and quiet, so I'm not concerned with my drives freaking out and
spontaniously dying.

So the current installer does not support the motherboard's RAID,
which is slower, but what about setting up linux's kernel's RAID?  Can
the current Sarge installer do that?

Also, I know about RAID 0, 1, and 50, but what on earth is RAID 5 and
6?  I think RAID 5 has to do with networked JBODs, but I'm not sure...
raid4: 2 or more disc with the data spread around, 1 with checksum
if one disc fails you still have the data...
raid5: the same with one exception: instead of having one disc deticated to cheksum, it is spread around the disc (first block data-data-checksum, secound data-checksum-data, and so on)

point is: you do not duplicated the data, you just loose the capacity of one disc (cheaper and less data to be writte to the discs...so in the best case faster/nearly as fast as raid0 in reading)

raid6: a quite new mode witch alows to discs to fail before losing data...
