It will gain you about a meg (one cylinder), but will cause all kind of
trouble when you're not very carefyll. lilo, other OSes installers,
user errors can easily cause the rewriting of a MBR. This will kill your
PV, and the VG it belongs to.
Some readers already had this happen, and it was QUITE a pain to recover
the data on the affected VG (I'm not sure if everyone was able to
recover their data, for sure some were (with the help of Heinz IIRC))
