an additional data point:

it's worked for me on several machines. my upgrade procedure is to
use dselect with apt as the install method rather than just 'apt-get
dist-upgrade' - this allows me to select which new packages i want
to install as well as upgrade all the old packages. it also avoids
conflicts/depends/ordering problems caused by packages being renamed -
dselect resolves them before apt is asked to do anything.

to avoid problems with overwriting files, i created an /etc/apt/apt.conf
file with the following lines:

---cut here---
DPkg 
{
   Options {"--force-overwrite";}
}
---cut here---

i've wanted that feature in dpkg for ages (for me it's more important
for an upgrade to complete smoothly than it is to know about packages
which don't properly use diversions). apt now provides it, so i'm happy :)
