Many of these laptop processors are soldered on so they can't be replaced. The best solution for you is going to be to pick a new laptop that does have a processor that supports VT-x. You can check to make sure that the processor has support for VT-x from http://ark.intel.com/
Most laptop cpus are not soldered and the c2d t5000 series does not even have an embedded option. However I wouldn't say any c2d is going to work well running vmware and wouldn't suggest going with a higher tdp c2q.
There is no way to run mac software on windows. Either virtualize, hackintosh, or buy a mac.
