> wacom: version magic '2.6.11 gcc-4.0' should be '2.6.11 gcc-3.3' You have been compiling the wacom module with a different GCC version then the kernel itself was compiled with. If you compile the module with the same compiler as the kernel was compiled (e.g. by changing symlinks in /usr/bin), it should not complain anymore. Just ask, if you need more specific instructions.
