Do you have a commit id? Looking at: http://git.linux-mips.org/?p=ralf/linux.git;a=commitdiff;h=1dfef20a4cf82997d4c7520138ed8188a181241c I'm guessing "1dfef20a4cf82997d4c7520138ed8188a181241c" is the commit id. Subject is: "brcmsmac: remove PCI_FORCEHT() macro" Description is: The BCM4716 is a SoC and does not have a PCI client interface, so this condition is never true.

I'm not actually. Currently exploring a device with ASUS's minimal shell they give you. According to /proc/cpuinfo, "system type: Broadcom BCM4716 chip rev 1 pkg 10". If I'm looking at the correct byte in /sys/devices/[...]/config, it does in fact appear to be 0x0A (decimal 10). I've seen photos of some people in Taiwan who soldered something at V11 (presumably a voltage regulator, it's all Chinese to me). I'm guessing they did in fact get a MiniPCIe card to work, but everything is in the wrong language. :-) The crucial build photo of the regulator module has disappeared, so it is more difficult to reconstruct. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | EHeM+sigmsg@xxxxxxx PGP F6B23DE0 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 2477\___\_|_/DC21 03A0 5D61 985B <-PGP-> F2BE 6526 ABD2 F6B2\_|_/___/3DE0
