i actually managed to build some modules for Kirkwood Kenel 3.3.4 (which i use in LS-QVL)
You can download it from here: https://www.dropbox.com/sh/0t4tw0qlgaxgb5d/AAB0rAa-9aT0YF-XO8quhotpa?dl=0
Most interesting might be the modules like pl2303.ko, ftdi_sio.ko, but i also built some dvb-modules and many more. They are all in the archive.
I also built modules for Armada 370 Kernel 3.3.4 (file armada-modules.tgz) for LS4XX/LS2XX which was really a mess, because
I had to change a lot in the sources to get them build.
I cannot test them due to lack of hardware.
This is my contribution to a forum which helped me a lot in the past.
Last words:I give no guarantee that these modules work and that they won´t do any harm. You use them on your own risk.!
I am not an expert, i had to do a lot try and error, but at least the modules for Kirkwood are working on my LS-QVL.
Have a nice day
