You should use the patches joe submitted to l-k recently together with
the userspace library and tools in the tarballs on the ftp site.

Snapshots and pvmove are still being ported to 2.6.

Patches:
  http://www.ussg.iu.edu/hypermail/linux/kernel/0307.1/1023.html
  http://www.ussg.iu.edu/hypermail/linux/kernel/0307.1/1025.html

[remove the blk.h includes now to patch cleanly]

I've been running the  LVM2.2.00.01-rc2 and device-mapper.1.00.01-rc2
code with Joe Thornber's 'dm v4 ioctl' patch, and it works just fine except
for the lack of pvmove.

i just built (successfully, i think :-) LVM2 under 2.6.0-test1-ac2,
and without testing it yet, i noticed that there is, in fact,
a "pvmove" command.  does that mean that all the pvmove functionality
is there now?  or what does it mean?

pvmove will only work with 2.4 kernels so far. 
It is still being ported to 2.6.

If you attempt to run pvmove on 2.6, it'll fail and you may need to run 
'pvmove --abort' to clean up the (failed) metadata changes.
