Anaconda+small-mem+lvm-swap crash

["Barton, Christopher" <cpbarton uiuc edu>]

FWIW -- Anaconda crashes for me when I install over NFS on a box with 256
Mb of memory & place swap on LVM.  The installer says that it needs to
activate swap space in order to continue, and then reports a problem and
quits.

When I place swap on a primary partition (instead of LVM), the install of
Severn completes without any trouble.
