Php-Nuke at GoDaddy

Does anyone have any experience running any kind of php with MySQL
backup at GoDaddy? I need to install Php-Nuke for a client and the two
critical things I need to do, untar the set of portal sites, and a mysql
databasename < nuke.sql , doesn't seem to be possible.

I'm still corresponding with their tech support. Anyone have personal
experience with this?
