I just tried it with the latest (supped 2:00 MET) -current kernel and config.
The patchs applied cleany (minus a minor glitch in GENERIC), and I have
been able to compile a GENERIC kernel without problems.

I guess config didn't generate a correct acd.h for you. Try removing the
kernel compile directory and config it again.
