Bleeding edge graphics

All;

I’ve downloaded the following

kernel-source-2.6.28-next.20090107.2.4.x86_64.rpm
libdrm-2.4.4-1.1.x86_64.rpm
Mesa-7.2-13.1.x86_64.rpm
xorg-x11-driver-video-7.4-26.1.x86_64.rpm

so that I may incorporate all the improvements in the Intel graphics drivers.

I’m a bit leery to install them with

rpm -U *.rpm

for fear I will break my OpenSuse 11.1.
I’m I being rational, or do these packages work well with a standard installation?
