Hi Daisaku,

I have a nasty feeling that I've recently broken this by rejecting
mmap() requests to very low virtual addresses.

Please pull the very latest unstable tree, build it, and when you
start X please look on the kernel console (e.g., by using dmesg) to
see whether you get a line of the form:
 WARNING: Preventing a mmap() request by XXX at XXX, len XXX

If you do then this is a problem that I can fix. :-)
