I have SCO Xenix, but will try to answer your questions.  I believe that
SCO Xenix is very similar to your IBM Xenix.  First of all, it is pretty
easy to get uname to return the correct node name.  In the directory
/usr/sys/conf there is a file called 'master'.  Towards the end of the
file,  you will see a line that says:  node  NODE  "Xenix286".  Just
edit your sitename in, save the file and type make to make a new kernel.
Install it as /xenix, reboot and you have a working uname call.

I have heard a number of people complain that the uname call in pathinit
messes up the stack.  I believe that these people were using the medium
model of the compiler.  I used the small model, and my inews work just
fine.  If worse comes to worse, you can always use /usr/include/whoami.h
code included for v7 compatibility.

The distributed version of compress works perfectly, just define pcxt
when you compile it.  It only does the 12-bit compress, but that is
an unfortunate side effect of the 80286 architecture.

In short, don't give up.  I know an awful lot of sites successfully running
news under various flavours of Xenix.
