Not sure it can help, but still: the documentation of pdfTeX /usr/ 
local/texlive/2007/texmf/doc/pdftex/manual/pdftex-a.pdf says on p. 40

Since pdfTEX 1.30.0 also the alpha-channel of png images is processed  
if available; this allows
embedding of images with simple transparency

So it seems that if you can prepare a png version of the logo with the  
required transparency, then this transparency will be honoured once  
the png file has been included in the pdfteX output. Or did I  
misunderstand something?
