FrontPage support is available, at least it is as much as it is anywhere else on a linux platform, but you should understand that MicroSoft is *not* releasing any new server extensions for *nix and there *are* problems with the ones presently available. (google can show you a lot about the demise of FrontPage)
That said, you *can* use FrontPage as a page editor, and you can *publish* using FTP, without having FrontPage extensions installed on the server as long as you do not use the Front Page features that require the extensions.
If your site *does* utilize features that require them, you will have to either enable them for your domain (and deal with the resultant issues) or re-code those parts of your site using standard web tehnologies (CGI, php, etc.)
You might find useful information in this DH WIki Article on FrontPage.
Given that Microsoft has abandoned the product, it is also time to consider approaching your "work" about moving on to a more stable and modern toolset - that Google search about the future of FrontPage, and it's current state, should give you plenty of information to make your case that, unpleasant as it may be, it is definitely time to change.
Hey, we all use the tools we have and the tools we know, but sometimes we'll all just have to move on.
