The EZ18 works fine in Fedora Core 3 and 4. Audio and network will be automatically detected and require no interaction. The nForce GPU is supported, but requires an external nVidia driver for 3D acceleration. The default (included) driver is 2D only.
The Unofficial Fedora FAQ has published installation instruction for the nVidia driver:

A final note: This 3D driver seems to work only with the 32MB or 64MB shared graphics video setting in BIOS setup. Changing this setting to 128MB will cause the driver to crash immediately.
