This is the error message if you compile with a type P6 file:

DEBIAN  drivers/video/logo/logo_linux_debian.c
drivers/video/logo/logo_linux_debian.ppm: Binary PNM is not supported
Use pnmnoraw(1) to convert it to ASCII PNM
make[5]: *** [drivers/video/logo/logo_linux_debian.c] Error 1

And *pnmnoraw* is what I was looking for.
Thanks again Florian!
