Sure,
we'd need some modules related fixes (autoload, rrecommends) for our devices.
About hostap, I was thinking those would be added by the fragments
inherited by spitz:
include features/hostapd/hostapd.scc
include features/mac80211/mac80211.scc
Something is wrong then..I'll check what is missing...
Finally, as you have surely noticed, the kernel size is huge, many
stuff should be built as module.
I'm testing now some contermeasures (e.g. nocfg).
Cheers
