 Ghostscript does this, but is unable to convert gradients and fills
 (they're replaced by bitmaps) which results in a too big file unless I
 drastically reduce quality.
 

Have you tried inkscape? it is in portage.

 I don't understand what you're asking for.  What sort of output format
 do you want (raster, vector, ???)?

I think he wants the same PDF as the original file. Only in grayscale.

This is one method to do this, but it needs Acrobat 8 Professional:

Are you the creator of the document and want to save the original as
greyscale, or you want to convert an already existing PDF?

If the latter I think the easy way is to use ghostscript (pdf2ps) to
render it as greyscale postscript. Then you could convert the PS back
to PDF if you need to. But if you already tried that, then, I don't
know...

Use the GIMP, Luke. I have to do this all the time with forms and
such. The GIMP imports PDF files nicely, and I usually print the file
to PDF after I am done. Now, if you have a many page document, the
GIMP will import each page as a layer which can make it a pain to have
to manually print each layer as a separate pdf, but ya do what ya
gotta do. I also like PDFShuffler for managing/mangling pdf files. Its
in portage by the way.
