I tried the patch but it would not apply to 2.6.20.7 and
appeared to already exist in that release as patch was
asking me about reversing the patch. So I just built a
vanilla version:

Linux otv2 2.6.20.7-i686 #1 SMP Tue Apr 17 02:33:19 BST 2007 i686 GNU/Linux

and then tried the mount again:

otv2:/dma/FloppyDisks-3.50# mount -t ufs -o ro,ufstype=nextstep,loop NeXT-Diagram1-fd0a.ufs /floppy
otv2:/dma/FloppyDisks-3.50# df

otv2:/dma/FloppyDisks-3.50# ls /floppy
ls: reading directory /floppy: Input/output error

I find in syslog:

Apr 19 17:34:29 localhost kernel: UFS-fs error (device loop0): ufs_check_page: bad entry in directory #2: directory entry across blocks - offset=140, rec_len=884, name_len=7
Apr 19 17:34:29 localhost kernel: UFS-fs error (device loop0): ufs_readdir: bad page in #2

I would be happy to supply you with an image of the NeXT /dev/fd0a
floppy partition if you would like, or even a full image of
the floppy made via the NeXT raw device /dev/rfd0b.
