Well you are right .... but for a lighter CMS that will work great for Hosts such as Bizhat, i just discovered LIMBO.... of cause LIMBO is a light weight version from Mambo, though it was not developed by the same developers.

It does not make use of mysql databases. It creates a text file that stores all the information. So once you have achieved your php access, I'll recommend LIMBO for the best CMS to use...
