That explains why the patch below never worked on my Q950. I never sent
the patch because I figured there was something, well, fixable. It works
on CUDA. I think I tested Mac II ADB too, but I don't remember the
results.
I'm pretty sure that Roman's "move to adb/via init" comment* related to a
build failure that Al Viro since fixed**.
