That I haven't tried... actually none of the 0.90 or 0.50 RPMs I've
grabbed have any such file in them (both official and non-official
RedHat RPMs).

Hmmm... does RAID-0 need upgrading? I've never gotten mkraid in 0.90 to
work.

I have 2.2.10-ac4 running... I'm moving to -ac12. I run -ac patches for
a couple of reasons:
- Help test out the patches for Alan
- I have an on-board aic7xxx based SCSI controller and 50% of the time
Doug's changes break support for my controller... I like to catch those
before they make it into a released kernel
- I have an SMP machine and have problems with the random and infrequent
system lockups... this is being played with in the ac patches
- I have a SCSI scanner and the sg driver has major problems...
sometimes the ac patches play with this (I'll probably have to wait for
a reasonably stable 2.3.x to get any real improvement)
I think some raid patches are already in 2.2.10-ac12... the latest raid
patches on ftp.us.kernel.org:/pub/linux/daemons/raid don't apply...
every file/patch it adds patch thinks is already added.

MD is compiled in. RAID0 is a module... I tried manually loading the
module. I do have RAID0 working perfectly (well almost) under 2.2.10-ac4
and several kernels before that.

Thanks... I'll take a look.
