Strange. It does work, however, if I don't specify the resolution. Same 
thing if I call gs by hand...

GPL Ghostscript 8.64 (2009-02-03):
gs -r300 -sDEVICE=pngalpha -sOutputFile=file.pdf file.pdf
 => no alpha
gs -sDEVICE=pngalpha -sOutputFile=file.pdf file.pdf
 => perfect alpha, but low resolution (basically as it's supposed to be)

Forget about this, sorry about the noise. I'm wrong, pngalpha works just 
fine. As long as it works, i. e.
