Did your genkernel boot OK, before you enabled 'CONFIG_.*80211'?
What output does the command line shown below return?
grep '^CONFIG.*80211.*=[nmy]' /usr/src/linux/.config
Here's what I get on my system:
CONFIG_CFG80211=y
CONFIG_CFG80211_DEFAULT_PS=y
CONFIG_MAC80211=y
CONFIG_MAC80211_HAS_RC=y
CONFIG_MAC80211_RC_MINSTREL=y
CONFIG_MAC80211_RC_MINSTREL_HT=y
CONFIG_MAC80211_RC_DEFAULT_MINSTREL=y
CONFIG_MAC80211_LEDS=y

I assume you also ran 'genkernel all' after running 'genkernel
--menuconfig', didn't you?

What's the contents of your /etc/conf.d/modules?

/etc/fstab?

and what's the output of 'mount|grep ^/dev'?
