Graphical installer.
On a machine with 16Mb, after Disk Druid I get a message saying 'As you
don't have much memory in this machine, we need to turn on swap space
immediately. To do this we'll have to write your new partition table to the
disk immediately.  Is that okay?'.  Pressing OK just returns me to Disk
Druid.  On VT1:
