This is certainly not a RTAI related thingy. The Intel Pro/1000 driver
has changed recently (dunno what kernel version), the e1000e you see
with your FC9 kernel is the new driver for Pro/1000 PCIe devices which
is probably the case for your card.

Dive into drivers section of your vanilla kernel and check if the
Pro/1000 driver for PCI express and / or the old e1000 are enabled.
