Does the PCI core on OpenCores support DMA? I don't have any

Hi Nathan,
Xilinx ISE allows the combination of module files written in either
verilog or VHDL. If you add modules, there is an option for you to
select the appropriate language. 

There are also available tools for you convert code from Verilog to
VHDL, try this script: http://www.taudelta.com.au/v2vhd.html 

Hope you can provide me some reference design too, i am interested to
your experiment. 

Thanks,

Ricky
