Missing .../m68k/conf/GENERIC

I'm apparently missing something very obvious, since I can't find any posts
about it on the net. The problem is that I was about to start patching
OpenBSD 3.5 on a Macintosh Quadra 650, when I noticed that I can't find any
/usr/src/sys/arch/m68k/conf/GENERIC file. All the information and posts I've
found on kernel compilation on the net, points to this file. Still I wasn't
able to find such a file for this arch even under
http://www.openbsd.org/cgi-bin/cvsweb/

When having a quick look at other archs, I noticed that at least for
powerpc, the case seems to be the same, no GENERIC...

Please advice me.

Thanks in advance,
