I can only think that something is inconsistent in your proj setup, e.g.
maybe mixing a custom proj library with the system projection or datum
definitions.

Can you see which proj library cs2cs & osm2pgsql are using?
Something like this:

$ ldd osm2pgsql | grep proj
        libproj.so.0 => /usr/lib64/libproj.so.0 (0x00007fd198360000)

$ type cs2cs
cs2cs is hashed (/usr/bin/cs2cs)
[jburgess at shark osm2pgsql]$ ldd /usr/bin/cs2cs | grep proj
        libproj.so.0 => /usr/lib64/libproj.so.0 (0x00007ff3a4468000)

Then if you feel like digging deeper to see what the code for each
program does when asked to initialize the projections then collect the
strace output:

$ strace -o /tmp/osm2pgsql.txt -f osm2pgsql great_britain.osm.bz2
$ strace -o /tmp/cs2cs.txt     -f cs2cs +init=epsg:4326 +to +init=esri.extra:900913

Then compares the output in cs2cs.txt vs osm2pgsql.txt. There will be a
lot of information in there. Towards the end you should see it opening
and reading various proj data files from /usr/share/proj (or similar).

If you get stuck, try attaching them to an email and send direct to me.
They will be too big for the email list.
