Take a look at the following post:

http://groups-beta.google.com/group/microsoft.public.dotnet.xml/browse_frm/thread/383d0253b40c0da8?hl=en&lr=&ie=UTF-8&rnum=8&prev=/groups%3Fq%3Ddotnet%2520XmlSerializer%2520cannot%2520convert%2520type%26hl%3Den%26lr%3D%26ie%3DUTF-8%26sa%3DN%26tab%3Dwg

It describes a solution to the jagged array limitation in XmlSerializer that
will hopefully be useful.
