Zpool not recognized after disk moved to different name

Hi, I'm migrating a system exhibiting the click of death to a new hard
drive, on PowerPC, and in the process migrating to zfs.  I set up the
system, then pulled the old drive out. Now, the spool that was on ada1s5 is
now on ada0s5, and zfs won't recognize this pool. I can't recreate the
pool, it says it is too dangerous.  Is there any way to reactivate this
pool after the disk name change?

Thanks,
Justin
