wine users - Jun 2012 - How to revert to wine 1.5.4 on Ubuntu 12.04 using Synaptic?

I am using:
http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu
as an additional repository in Synaptic so I can use the latest (released)
version of wine, 1.5.

Today, with the wine 1.5.5 update, I can no longer run World of Warcraft, so
I'd like to revert to the 1.5.4 version until the latest released version
works.  Unfortunately, I can't force Synaptic to use 1.5.4 (perhaps because
the repository no longer offers it? I'm really not sure how this works).

Is there a way I can get Synaptic to use 1.5.4?

[I realize that I could in theory download the git and compile it, but I've
had no luck following the instructions for downloading, patching, and compiling
on a 64-bit system based on the existing instructions in the wiki when I tried
that a few weeks ago.]

(Couldn't do it using synaptic, but found some help in backing it out on the
appdb page for WoW:
http://appdb.winehq.org/objectManager.php?sClass=version&iId=24878)

sudo apt-get remove wine1.5 && sudo dpkg -i `find
/var/cache/apt/archives/ | grep "wine" | grep "1.5.4"`

This command worked for me.  Would still appreciate an answer to my original
question, if there's someone with more knowledge of Synaptic who can help
out.

In RPM based distros there is a downgrade functionality in the package manager:

$> yum downgrade wine

Maybe apt-get has something similar implemented.
