I missed what kind of modem you have.  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
