squeeze, setup-storage and LVM

It's truely easy to make setup-storage eat this extra 'i', but what is the
correct solution? It seems that LVM switched over to IEC-proposed Gi prefixes to
mean 1024*1024*1024 bytes; should we then also change the semantics of
disk_config files where

disk sda
primary  /  80G  ext3  rw

means 80 * 1000 * 1000 * 1000 bytes and is actually smaller than

disk sda
primary  / 80Gi  ext3  rw

?? 

I guess this will cause quite a lot of confusion, but it would in some sense be
"correct".

For the moment I'll just add a eat-the-i-patch to setup-storage.

Best,
Michael
