openwall is for 2.0.x and 2.2.x kernels. version for 2.4.20 is still considered unstable by solar designer. grsecurity started (afaik ) as openwall port to 2.4.x kernels. but grsecurity now offers much more...

rsbac is more complex, provides several security models, more flexible and stronger in some areas, but harder to configure and maintain.
