Does that imply, that lvm snapshots should work with 2.6.0
kernels? 

When I try the following (ok its xfs but ...)

xfs_freeze -f /home
lvcreate --size 250m -s -n snap1 /dev/vg00/home_lv 
xfs_freeze -u /home

I get this error:

  Rounding up size to full physical extend 252.00 MB
device-mapper: error adding target to table
  device-mapper ioctl cmd 9 failed: Invalid argument
  Couldn't load device 'vg00-snap1'.
  Problem reactivating origin home_lv
      
?! 

With a patched Debian kernel that worked ok with 2.4.22 (IIRC).
