Hmmm... the situation is a mixed bag.
1.5.3 has support for 900913, but the projection is not implemented
correctly and result are a bit off, even for WMS. Moreover, 1.5.3
implements only WFS 1.0 that has no support for reprojection (that's
a protocol limitation).

1.6.0beta3 has a correct reprojection for WMS, and can reproject
data in WFS for WFS 1.1, but I'm not sure about WFS 1.0 (we were
in mid air trying to add reprojection to it as well, even if the
protocol does not support it natively).
1.6.0beta4, that you can already download from sf, should have
both of them working correctly for WMS, WFS 1.1 and WFS 1.0.

If you have more problems, don't hesitate to contact us on the
GeoServer users mailing list or on the IRC channel.
