I am rather puzzled as to why you chose to eliminate
not just fixed DH, but also the ephemeral finite-field
DH key exchange.  What's wrong with the DHE ciphers?

I would have chosen:

	HIGH:!aNULL:!kDH:!kECDH:!MD5

which excludes the *fixed* DH/ECDH ciphers and MD5
(and thus also SSLv2).  This does not eliminate
ephemeral finite-field DH, not sure why you're doing
that...
