I have a Diamond SupraMax, and it won't work. If you look at the current Red Hat hardware compatibility list, they mention that Diamond memory-mapped PCI modems are not currently supported in the kernel. I have contacted Diamond about getting enough info. to write a driver, but I haven't heard anything back. I don't know if other modems use a similar scheme, but you might want to check on the Red Hat site (www.redhat.com -- go to installation support, then down to hardware compatibility lists).
hope that helps, Joe
