[driverloader] "Invalid module format" error on AMD64 w/ kernel 2.6.10

[Linuxant support (Jonathan)]

Hi,

you must not only uncomment the line "CC=gcc" in the file 
"modules/Makefile", you must also change it to point it to an 
installation of gcc 3.3.x on your system. For example, it could be 
"CC=/usr/local/bin/gcc" or "CC=/usr/bin/gcc-3.3" depending on how you 
system was configured.

Alternatively, you could try to download your gcc version to a 3.3.x 
version to be able to build kernel modules for your '2.6.10-9-amd64-k8' 
kernel. You could also instead install a kernel which was compiled with 
gcc 4.0.x.
