[linux-lvm] LVM1 -> LVM2 with failed disk

I've been running debian lvm10 on my machine because 2.4.22 didn't have
dm support and I couldn't figure out how to get the patches working.
I've since upgraded to 2.4.27 but never upgraded to lvm2. I do run in on
two other machines.
Of course, one of my disks died. In the past, I used the -P partial flag
to get the lvm to start so I could copy off my data from the "good" pv,
but under lvm10, I don't see that option.
What are my options. Can I upgrade from lvm10 to lvm2 with a failed
disk. The lvm doesn't start and while I can pvdisplay /dev/hda4 I cannot
vgdisplay or lvdisplay (obviously) since the vg isn't starting.
Can I put in a dummy drive, somehow tell lvm to pvcreate a pv on the new
drive with the same ID and then get the vg to come up?
Any other ideas. I'd like to salvage the data that is physically on the
