setup-storage does not preserve my partitions

[Nicolas Courtel]

Hello,

To install a multi-boot Vista/Lenny laptop, I need to preserve the first 
2 primary partitions of the hard disk.
So I tried the following setup on a test machine, with empty partitions:

disk_config sda preserve_always:1,2 bootable:3
primary     /boot     512    ext3    rw
logical     -       22000-    -    -

disk_config lvm
vg vg0 sda5
vg0-swap    swap     2000    swap    sw
vg0-root    /        6000    ext3    rw
vg0-var     /var     2000    ext3    rw
vg0-usr     /usr     6000    ext3    rw
vg0-local   /local   6000    ext3    rw

The installation works fine, but does not preserve my partitions, /boot 
goes to sda1. The log is on http://paste.debian.net/18763/.

Any clue?
