The National Post is perfectly willing to have their site display differently in various browsers, and are okay with their article page header text changing a tiny bit, a split-second after it loads.
They apply the following font stack, along with a custom @font-face linked web font, to their article pages, leaving their homepage clear of web fonts:
48px/1em 'PostSansMedium',helvetica,arial,sans-serif
They use Wordpress, too.
So this is a good example of one very high-profile company who's on the @font-face bandwagon.
