most of problems below are due to 2.2 kernel.
the cvs version is not tested well on 2.2 kernels (also i tried only
i386)

it seems that configure script didn't detect these checks correctly.
could you check config.log ?

it must be harmless since the function will be never used unless the
driver is built into kernel.  (should be fixed, though)

grrr, they don't exist on 2.2 kernels...
we need a wrapper for them.

defning __NO_VERSION__ seems missing.
put #define __NO_VERSION__ at the beginning of each au88?0.c.
