Installed this update to the last update this morning without any issues for 11.3 64bit on a lenovo SL510.
I too applied it on all my installs
Works fine, trouble free.
Yes, I just updated the kernel without any problem. It also reinstalled the kernel-source and Nvidia driver automatically.
Me too installing without any issue on x86 platform 
It went well. here too

All well here too, found out today that the NVIDIA driver from the repo does work after a kernel update…
It installed fine for me but after a couple days it locked up so I returned to 2.6.35 as my daily use kernel.
It’s always worked for me. I have yet to have to manually get my video going yet after a kernel update using openSUSE. I keep my fingers crossed though.
