[linux-lvm] lvm1 physical volume unaccessible after too big lv expansion

I'm getting into big trouble with a lvm1 physical volume 
after I wanted to resize a logical volume and lvresize barked
something like
  "cannot grow a lv more than 64K extents"...

The problem is after that I cannot access my data...

I copy the output of pvdisplay -vv and pvscan at the end
of the message...

Trying to go any further tells me it did not find the volume group...

Any idea ?

I'm using ubuntu on a ppc (powerbook)

root at ubuntu:/home/ubuntu# pvdisplay -vv /dev/sdc
      Setting global/locking_type to 1
      Setting global/locking_dir to /var/lock/lvm
      File-based locking enabled.
    Using physical volume(s) on command line
      /dev/sdc: lvm1 label detected
      Reading physical volume data /dev/sdc from disk
      Found /dev/sdc in VG vg
