Solved.
Abiword-2.2.7 has the print command enabled. Just choose to print to filename.ps, and
it will create a filename.ps (postscript) file. Then, the command is_

ps2pdf filename.ps filename.pdf.

I don't know at present if the ps2pdf binary I found on my n800 is there by default or comes from the kde environment by penguinbait.

There is still the problem of bad rendering of images in my tests but this seems enough by now :-)
