Well, COMPAT_43 one isn't even in GENERIC anymore, so I guess it is not that

This is still in the GENERIC kernel. I'd keep it in initially. Then build a
kernel without it. If that fails to start the system properly, you'll always
have a good kernel to fall back on.

Have a look at what is written under COMPATIBILITY OPTIONS in /sys/conf/NOT=
ES.
