To address only the Atheros questions, yes it works, no CentOS doesn't
spin up the drivers themselves. I have an R40 (2682-48U) and I don't
build my own drivers, but you can get them in RPM form at the atrpms
repo. Check out the Repos from the wiki if you want to know how to add
atrpms.

Everytime there is a kernel upgrade, I just wait a few days until the
new madwifi items are re-spun from the atrpms folks, and life has been
good with my wireless for over 2 years now.

I've never fired up my modem, so I'm sure if it works or not. But I can
tell you my Atheros chip functions.

rpm -qa | grep madwifi

madwifi-hal-kmdl-2.6.9-42.0.8.EL-0.9.2.1-29.el4.at
madwifi-kmdl-2.6.9-42.0.8.EL-0.9.2.1-29.el4.at
madwifi-0.9.2.1-29.el4.at

These would be the three packages you need from atrpms for it to load up
your wireless. You can compare my model R40 with yours, and if you need
any hardware comparisons, just let me know.

lspci -v for my Atheros shows:

02:02.0 Ethernet controller: Atheros Communications, Inc. AR5211
802.11ab NIC (rev 01)
        Subsystem: Unknown device 17ab:8310
        Flags: fast Back2Back, medium devsel, IRQ 11
        Memory at d0200000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [44] Power Management version 2

Aside from that, I've been extremely pleased with running CentOS on my
R40. I get all the multimedia items from Dag. Xine works great for DVDs,
and XMMS or mplayer for MP3s.

It's extremely stable for me. The only issues I've ever hard are the
fact that I can't get my machine to wake up correctly when I try to put
it to sleep, but I've never experimented much on getting it work either
so it might be something simple. I know I'm not answering your questions
about RHEL5, but I thought I would share my experience on my R40, and
specifically mention you can get the RPMs for your wireless through the
third-party repo.
