hmm, i updated to 3.10 today, and indeed i'm having problems as well,
e.g. with the proprietary fglrx drivers.
however, looking at the make.log for the failed build, it seems that
fglrx is indeed broken for that kernel.
while i haven't followed recent kernel development, it might be that
they just added/removed a bunch of things, thus forcing all external
modules to be updated.
this would mean that each affected module is indeed buggy and bugs
should be reported.

however, it seems that i do not have problems building v4l2loopback on
an amd64 machine:
# KBUILD_VERBOSE=1 dkms build -k 3.10-1-amd64/x86_64 v4l2loopback/0.7.0
Kernel preparation unnecessary for this kernel. Skipping...
Building module:
cleaning build area....
make KERNELRELEASE=3.10-1-amd64 -C /lib/modules/3.10-1-amd64/build
M=/var/lib/dkms/v4l2loopback/0.7.0/build.....
cleaning build area....
DKMS: build completed.
# ls /var/lib/dkms/v4l2loopback/kernel-3.10-1-amd64-x86_64/module/
v4l2loopback.ko
so maybe you have some other problems, e.g. with your compiler.
does the gcc used for compiling the kernel/module actually work?
the following only works because i have run dkms with the
"KBUILD_VERBOSE=1" environment:
$ grep gcc
/var/lib/dkms/v4l2loopback/0.7.0/3.10-1-amd64/x86_64/log/make.log | awk
'{print $1}'
gcc-4.7
$ gcc-4.7 --version
gcc-4.7 (Debian 4.7.3-6) 4.7.3
if this doesn't reveal anything, please post the make.log after you run
dkms with KBUILD_VERBOSE=1.
(check the make.log before posting; it should have plenty of complicated
gcc calls in there, instead of the elegant "CC [M]" in your original
make.log)
