I have found a workaround. If you do apt-get install dpkg (dpkg is
already installed so the effect is to upgrade dpkg) then it does this;

The following extra packages will be installed:
  liblzma5 multiarch-support xz-utils
Suggested packages:
  xz-lzma
The following NEW packages will be installed:
  liblzma5 multiarch-support xz-utils
The following packages will be upgraded:
  dpkg
1 upgraded, 3 newly installed, 0 to remove and 264 not upgraded.

Once this completes, you can then do the dist-upgrade without warnings

** Description changed:

  When doing dist-upgrade from (fully patched) 10.04 LTS x64 "Lucid" to
  12.04 LTS x64 "Precise" (beta1) you are warned;
  
  WARNING: The following essential packages will be removed
  This should NOT be done unless you know exactly what you are doing!
    lzma (due to dpkg)
+ 
+ 
+ I should note that the actual steps I followed from 10.04 were;
+ 
+ source set to "lucid"
+ upgrade
+ dist-upgrade
+ change sources to "precise"
+ upgrade
+ dist-upgrade
