i have managed to compile with no problems the at76c503-0.16 with
linux-2.6.22-r8 on amd64 and managed to load the module without problems
with modprobe. the problem as what i have seen may be due to the fact that
you didn't compile your new kernel in /usr/src/linux. if the kernel is not
compiled the module wouldn't compile fine.
switch to the 0.16 version and try to build it and see if it builds.
unfortunately i don't have a way to verify it cause i don't have any hw with
wich to try.
