I have a problem when compiling the ATI kernel modules. I get this error-mesage.

ATI module generator V 2.0
==========================
probing for VMA API version...
check results are inconsistent!!!
none of the probed versions did succeed.
aborting module build.

What does this mean and how can I solve the problem?
Knoppix v3.3, Kernel 2.4.22-xfs
