Errrrr, the no access to tty means that you didn't port X11R4.
Porting means you got it *working* not that you made it compile.
Xload needs to be ported, as the AIX kernal doesn't keep the load average
information needed. My understanding is that is is due to the crazy
security classifications. To make xload work, you need to calculate the
load average yourself. If you have BSD sourcesm it is easy to look in
the kernel, figure out how they do it, and then you simply need to
do the same thing. I would include the code to do this, but since it is
derivative of the BSD kernel code, that would probably be a no-no.
As for xterm.... the changes needed are something like:
