Does not work. Tested with experimental11:

disk_config:
disk_config disk1 disklabel:msdos

primary -       4G-      -       -

disk_config lvm
vg VolGroup00        disk1.1
VolGroup00-swaplv     swap    512      swap     sw
VolGroup00-rootlv     /       5G      ext3     rw
VolGroup00-bootlv     /boot   256      ext3     rw
