No, it is a bug in the kernel, and even loading them by hand doesn't help.
I do have the module in /etc/modules for the above attempt.

Indeed. There are the winfarm ones too.

i don't have the hardware for thos,e which is why i wrote this one. It seems
common knowledge that they need to be builtin for now though.

not necessarily, but i admit i am not all that knowledgeable about this.
Oh, and BTW, initramfs-tools generated ramdisks attempt to load the
atkbd/i8042 modules on hardware not having any ps2 support. Can anything be
done about it.
