Hi!
I have one. However it is not generic at the moment. You would have to calculate the needed values for the timing-generation yourself (atm it uses a pixel clock of 21.5MHz). However I have problems with the bandwith of the OPB-Bus. It seems that it is too slow to deliver the needed video data. The best solution I think is to merge the VGA controller into the RAM controller.

There is one that is loaded on the Spartan 3 starter kit. The source is available from the Xilinx web. You probably can get an idea of resource usage from it. The name of the subcomponent is opb_color_video_ctrl_v1_00_a. I don't know if it is a licensed IP.

You might want to have a look at the EDK reference design for the ML401 board:
It does have a PLB VGA controller in the pcores directory. The PLB is used for bandwidth reasons.

It is intended for their products but it is generic enough where it can be used with other designs.
