I am using Version 22.0.1229.94 Debian wheezy/sid (161065) of Chromium. I am not sure how different, if at all, the Squeeze version is.
In the menu on the top right go to settings. You can also type this in the address bar, chrome://chrome/settings/ Then towards the bottom it has a user section. Add new user, Delete this user, import bookmarks and settings.
That is where it is at, try it and see if it works. Worked great for me but I am using the wheezy/testing version. Also in that top right menu, it has three horizontal lines as an icon for me, where you found the settings is a zoom option. See if that helps at all with the fonts. If not there is an option in the settings section to change the webcontent font size. Click advanced settings to get to it.
To see what version of Chromium you are using you can either click on the about link in the menu or type chrome://chrome in the address bar. For more detailed information type chrome://version in the address bar.
