Whenever @font-face inexplicably doesn't work for me in the supposedly compliant browsers, I drop this in my .htaccess file. Supposedly some browsers won't load fonts hosted on other domains, and this bit of code troubleshoots that, but sometimes it is the only remedy to force fonts to load that are hosted on same domain as well. Generally its more of an issue with Firefox than with Chrome, but I just now used this to force fonts in Chrome while Firefox was working fine. Go figure.
<FilesMatch ".(ttf|otf|eot)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
Another inexplicably weird thing I have had happen with the @font-face syntax was that it wouldn't load font files properly with caps in the name. This only was an issue once, and after repeatedly banging my head against the desk troubleshooting @font-face a bunch of different ways, as a last resort I changed all font files and font-family name to lowercase characters, and it worked fine (I think that was an issue in ever-finicky IE, and only one website I was doing, exact same syntax on another website worked fine with upper and lowercase characters).
