It's in git now (screen-v4 branch). Good luck with testing :)

For the next time: please provide author's information for your patch.

Screen gets the system load average to display it.
These values are retrieve using syscalls for some platforms, and when no specific code is provided, by default, they are retrieved by "read /dev/kmem".

Currently screen for AIX platforms falls in the default code (read /dev/kmem).
The request is to provide specific code to get the system load average values using a syscall for AIX platforms, which is cleaner.
This avoids to keep open /dev/kmem during all the screen session.

Moreover, as the AIX kernel is compiled in 64 bits, the values currently returned are false when compiled in 32 bits.

Attached below a patch for version 4.4.0
