thus the point is if you need to disable TT mode by default, isn't it?
Now user-mode-linux is in debian "unstable" [1] and I need to provide a
config file as default configuration for the pkg: you suggested me to act
this way 

#
# UML-specific options
#
CONFIG_MODE_TT=n
^^^^^^^^^^^^^^^^
# CONFIG_HOST_2G_2G is not set
CONFIG_KERNEL_HALF_GIGS=1
CONFIG_MODE_SKAS=y

and rebuild the bin, didn't you?

Cheers
