Following is a repost of an excerpt of a set of fixes I sent to FSF:

-----------------------------------------------------------------------
The RS/6000 arrow keys don't work correctly under X11.

They can be made to work in x11term.c by removing the #ifndef
AIX/#endif duo from around the second stringFuncVal() routine, as well
as the duo around the if/then/else following case KeyPress in the
XPending() loop.

-----------------------------------------------------------------------
The RS/6000 backspace key, as well as PageUp/PageDown, don't work
under X11.  This can be solved in x11term.c like this:

    case KeyPress:
#ifdef AIX
      XRebindKeysym(XXdisplay, 0xff08, NULL, 0, "\177", 1);  /* backspace */
      XRebindKeysym(XXdisplay, 0xff55, NULL, 0, "\326", 1);  /* page up */
      XRebindKeysym(XXdisplay, 0xff56, NULL, 0, "\026", 1);  /* page down */
#endif /* AIX */

(This is case KeyPress in the XtPending() loop in x11term.c.)
-----------------------------------------------------------------------

Good luck; your mileage may vary...
