reprojecting WMS layer

I am still having the problem of reprojecting WMS layers into other projection.
USGS provides it's Urban color ortho coverage only in epsg:4326 and I would like it to be in either local UTM zone or local state plate.
I have wms_srs set and PROJECTION tag set to 4326 at the layer level and output projection set via the cgi interface (a method which works fine with reprojecting shape files) The 2 output image is almost identical. There is a small "rotation" effect visible if I switch back and forth from the 2 images, but when I overlay a shapefile layer on it (which is correctly reprojected) the original projection 4326 creates a nicely overlayed image, while the reprojected one has the WMS and shape layer messed up, they do not correctly overlay.
Can I send 2 jpg attachment to the list to demonstrate?
The question therefore: is there any known trick with reprojecting WMS raster layer as opposed to locally stored raster and shape layer? Did anybody has this problem before?
Help me out on this as I am stucked for weeks already.
Here is my mapfile:
SIZE 600 400
IMAGECOLOR 0 0 0
The 2 url which should generate to different projection of the WMS layer is:
Let me know if anyone has some idea of what's going wrong here.
