The version of the Windows MySql.Data assembly doesn't match
the version of the Mono assembly. Even the latest MySql Connector
distribution comes with different assembly versions. I really don't
know why the maintainer is doing that ....

You may try to put the following entries in your linux web.config:

		<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
				<assemblyIdentity name="MySql.Data" publicKeyToken="the correct 
token!" />
				<bindingRedirect oldVersion="x.x.x.x" newVersion="y.y.y.y" />

x.x.x.x == the version of MySql.Data for Windows
y.y.y.y == the version of MySql.Data for Mono
