yep, i was thinking about CONFIG_BROKEN2 already :-)

then i came up with: CONFIG_NON_GENERIC. All code that can break a 
normal bootup should be marked with that. Such as CONFIG_ROOT_NFS=y 
[panics on bootup] or CONFIG_EUROTECH_WDT=y [crashes on bootup] or 
CONFIG_SND_MTPAV [hangs on bootup] and the dozens of other config 
options i had to map when trying to bring up an allyesconfig kernel for 
the first time ;-)

auto-tests could then still build-test NON_GENERIC kernels but would not 
attempt to boot them up.

hm?
