If I add a space and put the text at the end of the last line with text already on it [...]
You need to append to the line that starts with "linux", not the last line. E.g. if you have something like this:
linux /vmlinuz-3.17.4-301.fc21.x86_64 root=/dev/mapper/fedora-root ro initrd /initramfs-3.17.4-301.fc21.x86_64.img
You need to change it to this:
linux /vmlinuz-3.17.4-301.fc21.x86_64 root=/dev/mapper/fedora-root ro amdgpu.ppfeaturemask=0xffff3fff initrd /initramfs-3.17.4-301.fc21.x86_64.img
