Yeah, the old software RAID code in stock 2.2 is fairly evil... here's
a link to the announcement from mingo about a RAID 0.90 patch against
2.2.18:

I'll keep you posted... there's no reason I should have any issues with
it.  I've actually had LVM + RAID 0.90 up and running several times on
other machines, but have inevitably run into one of the various problems
that ends in a panic, so I'm taking a vacation.

As far as "nasties" in the old RAID code, I think mostly it's just that:
OLD.  RAID 0.90 has been out for a very long time now.  Not exactly sure
why it hasn't been rolled into 2.2 yet, although I'm sure the linux-kernel
archives hold the answer.
