I've also tried to set val to 0, and I still get the same problem:

(XEN) DOM7: (file=mm.c, line=352) Could not get page ref for pfn 921c0183
(XEN) DOM7: (file=mm.c, line=2042) Could not get page for normal update

I'm puzzled. The pfn given there looks all wrong, and I'm not sure
what is wrong with this code. The page directory is taken directly
from start_info (pt_base). Does anyone see what I do wrong?
