Yes, there is. Essentially, PPC Macs require a graphics card with PPC-compatible ROM, either genuine cards for PPC Macs or x86 cards with reflashed ROM (may or may not work fully). Those AGP cards exist up to Radeon X850 and are 3D-supported. Then there are AtomBIOS-based AGP Radeon cards up to X1950, which MorphOS can also run with and support in 3D but won‘t display OpenFirmware or the Mac boot menu. 3rd option are PCI Radeon HD cards, which lack 3D support and also won‘t display OpenFirmware or the Mac boot menu.
MorphOS 3.11 may add 2D support for AGP Radeon HD cards, btw.
