valid swap partition and uswsusp

I've built three Etch systems this year. The most recent (last weekend)
seems fine, but its installation proceeded differently than in the past, and
so I'm confused.

I installed from the latest netinst CD. During "Select and install
software", the following came up:

"The swap partition that was found in uswsusp's configuration file is
not active. In most cases this means userspace software suspend will
not work for you and you will need to choose (or let uswsusp choose)
another partition. In some corner cases, however, this can be what you
want.

"Continue without a valid swap partition?"

One would think that answering "No" (continue without a valid swap partition)
would be a bad idea. In fact, it was the only way to get the installation to
complete.

I now find that I have /usr/sbin/s2disk, /etc/uswsusp.conf, and other
hibernation software that is not present on my previous two installations.
I did the same "software selection" on those but used whatever Etch (stable)
netinst CD was current.

As far as I can tell, I do have a valid swap partition despite the error
during installation. /proc/swaps has

Filename Type Size Used Priority
/dev/hda5 partition 1461904 524 -1

I have two questions.

1. What caused hibernation software to be installed this time but not in the
recent past?
2. Do I have a valid swap partition?

This could be related to bug 411727, but supposedly that was fixed. Thanks.
