I picked up an I9100 SGS II the other day and decided to extend my development of the SGS boot screen MOD to it and was able to port it the same day as not much as changed in the way the param.lfs operates. I know this works just fine on the EURO I9100 SGS II in which the param.lfs calls for logo.jpg but if it fails, you can always re-flash a stock param.lfs to restore the boot screen which I have also included. I have written this for (I897, I9000, T959, T959V and now I9100). Per XDA's rules, I'll just attach the RAR package as an upload at the bottom of this post.
If you appreciate my work, just tap THANKS or DONATE me a drink or two if you are feeling generous. Here is the read me in case you don't want to open it with an additional text editor:

ONLY USE THE LATEST BUSYBOX BY STERICSON TO ENSURE THIS WORKS BEST. IF YOU DON'T WANT TO USE THE SCRIPT FOR THE LATEST VERSION, BE SURE TO DOWNLOAD THE LATEST FREE INSTALLER OR DONATE VERSION IN THE MARKET BY STERICSON.
If the script doesn't work for you, it should if you have ADB installed, a rooted device plus the latest BusyBox (no offense but it's user error otherwise) just use root explorer to paste your logo.jpg in /mnt/.lfs AFTER running the custom param file via ODIN.
