I just reinstalled 10.5 and XCode and tested it. It definitely worked
on 10.5 and now does not work on 10.6
The Finder seems to update, so it must be detecting the change
somehow, but I can't get it working on 10.6 using the same code that
worked on 10.5
Could you test this over there to see? If you set the file's Open
With settings in the finder it will add a resource fork. Set up a
test app to watch that file with kqueues and it shouldn't fire on
10.6. I used both my code and Google toolbox's kqueue code. Both
were the same.

This is on a normal HFS+ volume, so it's not doing the ._ file
Anyone know if this was a change in 10.6? I don't remember getting
bug reports for my 10.5 builds.
You have it backwards.
I'm pretty sure this did not work in 10.5, except on UFS, and that
doesn't natively support resource forks.
In 10.6, we actually added support for a lot of FS-level kevents at
the VNOP_ KPI layer, which means that they'll apply to all
filesystems equally, but probably still not resource forks
individually (part of the removal of UFS support was to support
these events for programs that needed them on non-UFS FS types.
If you are getting errors now, it's probably because you asked for
events before that it was impossible for you to get except on UFS in
10.5, and now you are getting them for HFS+, and aren't reacting
correctly to them occurring. Generally, if something doesn't work,
you shouldn't be asking for it in old software, in case it starts
working in new software. I expect if you were to try this on 10.5
on UFS, you'd see the same sort of things.
