Ok ... anyone remember the notes about dt 1.1.3 not working for SE30s
   back a number of months ago?  I dug up the changes that Ken Nakata had
   sent me and did the same type of thing to this version ... and it does
   seem to have done the trick.  :^)

   Change the one mmap line to:

	if( ioctl(f,GRFIOCMAP,&physscreen) == -1 ) {

   ... and everything should be ok.
