In this connection, I have an example. I have a Netgear WG111 v2 USB
Wireless Adapter which does not get detected by CentOS 5.1 updated
with the latest 2.6.18 kernel released. This particular adapter has
the Realtek 8187 chip. However, Fedora 8 running on 2.6.23 detects the
adapter and also loads the correct module for it. This leaves me
wondering whether the adapter will ever be supported by the current
Cent OS 5.x kernel or the subsequent updates.
