Has anyone come across something like this exclusively in Chrome 10/Win?
Try this from a previous StackFlow question. Refer to the htaccess part, not the beginning:
font-face with wrong MIME type in Chrome
Also refer to this ticket with Google:

Last resort: re-generate your font with Font Squirrel.
