Well, I was advised that really I want to mount wd0e based on the 
partition table.  I tried that and got even more unpleasant errors:

in syslog:

Dec 11 09:16:58  /netbsd: wd0: no disk label
Dec 11 09:16:58  /netbsd: ntfs_readntvattr_plain: POSSIBLE RUN ERROR
Dec 11 09:16:58  /netbsd: ntfs_readattr_plain: ntfs_readntvattr_plain
failed: o: 0, s: 1177000
Dec 11 09:16:58  /netbsd: ntfs_readattr_plain: attrib: 0 - 287

... and on the console:
mount_ntfs: /dev/wd0e on /tmp/home: Argument list too long

Yeah.  I was hoping this way could work so that I could just get the 
[warranty] replacement hard drive from Big Blue and be done with it.

Hmm.

Anyone got a Knoppix CD?
