Go to Xilinx's site and look at their PCI core IP. The fact sheet for that core will tell you the devices that are supported.
Do you need bus master support or just target support?
Also, are you confusing PCI and PCI Express? They are not the same. There is 32-bit PCI at 33MHz, 32-bit PCI at 66 MHz, 64-bit PCI at 33Mhz, 64-bit PCI at 66MHz, PCI-X at 33MHz, 66MHz, 100MHz, 133MHz, and PCI Express at 1-lane, 4-lane, 8-lane.
Altera also supports PCI, so do the same at their web site.
