I submitted patches for MGP 1.03a to Itojun a while back for automatic advance
of pages on a timed basis.  This required consolidating the advance-screen code,
replacing XNextEvent with code to check both the keyboard and a timer signal. 
AFAIK, the patches were not incorporated into 1.04a  (Mew.org is too busy right
now to check).  They might be helpful to you.  Let me know if you'd like to see
them.
