	OK, I have rebuilt userland with :

$(SRCDIR)/kernel/configure \
             --with-kickstart-linkbase=0x100000 \
             --with-s0-linkbase=0x40000 \
             --with-roottask-linkbase=0x60000 \
             --prefix=$(BUILDDIR)/kernel/build)

and I obtain :

	This emulator only has 128 MB. I don't undestand following line:

kernel    (0x0011b000-0x00158ce6)   => 0x40101000

because 0x40101000 isn't addressable. Other question : I suppose that 
kernel is mapped in 0x00400000-0x00419560, 0x00600000-0x00600908, 
0x00800000-0x00801e38 and 0x00a00000-0x00a13000. How I can configure 
these addresses ? This configuration takes more than 10 MB only for kernel !

	Best regards,
