I've installed the latest Lenny packages from proposed updates
which contain the new default value for MMAP but I'm not able
to reproduce your problem neither with VT-x enabled nor with
VT-x disabled. Though on a Linux host. I suggest you to open
a bug report. I can not see any general VBox restriction which
should be triggered by preventing guest mmaps to addresses
below 4096. When you open a bug report, please don't forget to
attach the complete VBox.log file of this failing VM session.
Thank you!

Kind regards,

Frank
