  hang on, something just seems weird here. let me start again with:

$ make distclean

now i'm going to copy the .config file that was the basis of the
currently running kernel:

$ cp /boot/config-3.7.0-rc4+ .config

and i can certainly see that this .config has a number of
ATH9K-related config settings:

$ grep ATH9K .config
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_BTCOEX_SUPPORT=y
CONFIG_ATH9K=m
CONFIG_ATH9K_PCI=y
CONFIG_ATH9K_AHB=y
CONFIG_ATH9K_DEBUGFS=y
CONFIG_ATH9K_MAC_DEBUG=y
CONFIG_ATH9K_RATE_CONTROL=y
CONFIG_ATH9K_HTC=m
CONFIG_ATH9K_HTC_DEBUGFS=y
$

but if i run:

$ yes '' | make oldconfig

i get:

$ grep ATH9K .config
$

that is, all the ATH9K-related modules are deselected. i don't
understand that -- so it's not a "localmodconfig" thing, it's
"oldconfig" that's wiping out my ATH9K config settings. thoughts? am i
doing something invalid?
