Well, the errors start appearing at logical block 2. I tried it on two 
physical disks, 160GB each. It's okay I guess, I didn't really want to use the 
linear driver, just test with it.

Luckily, LVM2 does work, and there's even a Debian package for it. I just used 
it to combine three 400GB enbd-exported volumes, format with XFS, and mount 
successfully. Only problem so far is that it thinks a single 'physical' disk 
of a little greater than 1TB is actually 2TB+. It doesn't want to work with 
disks over 2TB. Hopefully it can *create* a volume larger than that... that's 
the next test.

I think my last stumbling block is that the current 2.5 md driver can't 
restart a previously created device, which I need to do on the servers. If I 
have to, I can go back to a 2.4 kernel there, though.
