Hi Ted --
Do you have CONFIG_EMBEDDED configured in (I think it's under General)? If so,
there is a new selection in 2.6.28 you have to check: CONFIG_FILE_LOCKING. The
patch went into 2.6.28, but lots of defconfigs weren't updated until 2.6.29 or
.30rc. OTOH I would have thought the 'default y' would enable it for you.
+config FILE_LOCKING
+ bool "Enable POSIX file locking API" if EMBEDDED
+ default y
+ help
+ This option enables standard file locking support, required
+ for filesystems like NFS and for the flock() system
+ call. Disabling this option saves about 11k.

If you get that working, a good how-to would be appreciated by lots of people
on the list, judging by recent posts.
