PCI to PCIe conversion...?

Hello Chums....
...!
In the unlikely event of me "upgrading?" from my AMD Socket A/PCI-AGP Mother board to an expensive AMD Socket AM2/939 PCIe Motherboard and Processor, what will become of all my various PCI cards, eg; Sound Cards, Modem Cards, TV Cards, LAN Cards, etc, etc....?
Are they compatible with the PCIe slots in the latest Motherboards...?
Or have I got to throw them all away, and purchase similar cards suitable for PCIe slots...
...?
