A simple-minded copy/paste to a patchfile in /usr/src named vchiq.patch failed with 

# patch < vchiq.patch
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|diff --git a/sys/contrib/vchiq/interface/vchiq_arm/vchiq_2835_arm.c
|b/sys/contrib/vchiq/interface/vchiq_arm/vchiq_2835_arm.c

Patching file sys/contrib/vchiq/interface/vchiq_arm/vchiq_2835_arm.c using Plan A...
patch: **** malformed patch at line 11: actual, pagelist->length, bi->buf);

I've refrained from tampering with the sources, did I do something else dumb,
like not strip the a/ prefix from the diff line? I expected a "file not found" 
error in that case.

For clarity, /etc/make.conf is absent, /etc/src-env.conf contains
WITH_META_MODE=

Thanks for the quick reply!
