[SOLVED] Intel 5300 wifi on new Arch64 install

Question

I just bought a new Sager NP9262 laptop (but not really... it's huge, heavy, and sports a quad-core Q9650 processor), and put 64-bit Arch on it.  I've managed to get everything set up on it except for the wireless chip, an intel 4965.  I've downloaded the correct firmware (iwlwifi-4965-ucode) and the kernel module exists, but there seems to be a more basic problem.  hwdetect --show-net doesn't list the card at all, and lspci -k gives a rather unhelpful line saying
Network controller: Intel Corporation Device 4235
and lists no kernel modules which could work with the device.  Ideas?

Answer 1

EDIT:  now uses 2.6.27-rc6, which I haven't tested.  For something I'm sure works on my laptop, set '_rc' to '-rc5' and '_git' to '-git9', and uncomment the various commented-out lines dealing with -git patches.
Okay.  First start with everything from /var/abs/core/kernel26 in a separate directory.  Then, replace PKGBUILD with this

Then, edit the pkgbuild, and uncomment lines 62 and 63, right below "stop here / this is useful to configure the kernel."  Run makepkg, which will extract the sources, patch them, and stop.  Run:
$ cd src/linux-2.6.26
$ make menuconfig
Go to Device Drivers ---> Network Device Support ---> Wireless LAN, and scroll down to "Intel Wireless WiFi Next Gen AGN."  Press 'm' to include this feature as a module.  Enable any subfeatures you want, by pressing 'y,' but be sure to enable "Intel Wireless WiFi 5000AGN."  Also, enable "Enable full debugging output in iwlagn driver," which is above "Intel Wireless WiFi AGN."  Exit menuconfig.  Run
$ cd ../..
$ cp src/linux-2.6.26/.config config
or on Arch64, run
$ cd ../..
$ cp src/linux-2.6.26/.config config.x86_64
Comment out the lines you uncommented in the PKGBUILD, run
$ makepkg -g >> PKGBUILD
$ rm -rf src # otherwise, it tries to patch an already patched kernel
and finally, makepkg!
Also, install the firmware:
