It's just that early 3rd party chipset AGP compliance was not great. The motherboards themselves were also sometimes cheaply made and had power regulation problems with AGP. It seemed to finally be sorted out by the AGP 8x era.
You can certainly run a Radeon on Super 7 and it might work ok. You can run much faster cards too, anything with 3.3v AGP support will work. Cards with aux power connections might work best because the load on the motherboard is probably lower. But for 3D games, K6 CPUs struggle to saturate even a Voodoo2. Back in the day one of the perks was the Radeon has full DVD decode acceleration which is about the only way to play DVDs smoothly on Super 7. NVidia only implemented partial DVD acceleration until the GeForce 4 MX.
