I would like to set up a Xoops-based site using my existing domain, which was acquired through and is hosted via Yahoo (U.S.) small business service (since I have had the account for a couple of years, and use it regularly, it doesn't make sense for me to go looking for another host if I don't have to).

I've confirmed that Yahoo small business service includes support for PHP version 4.3.6 and MySQL version 3.23.49, but I am unable to determine from the available Yahoo documentation if this means I would be able to install and administer a XOOPS environment via this Yahoo-hosted domain.

Any input would be appreciated, especially from other users who may have a site running on Yahoo.
