I may be wrong, but i think some kernel headers either are not found by the
compiler (see in the compiler output if there's a line like 'file not
found', and if it's there, perhaps installing linux-headers package will
help.) or are not compatible with this version of the pwc module.
If all the necessary headers are indeed here, please attach the full output
of 'make'.
Thanks, and have a nice day.
