porting driver to 2.6, still unknown relocs... :(

[LGW <large@lilymarleen.de>]

Hi again.

As I described before, I try to port an audio driver from 2.4.x to 2.6.x.

It compiles, but on load I get "module snd_echoaudio: Unknown 
relocation: 0" from dmesg.

I looked into arch/*/kernel/module.c, and this error appears if the 
loaded module contains a relocation other than R_386_32 or R_386_PC32 
(for intel).

Now I wonder, what would be an relocation type 0? The printk should also 
print the type in clear text I think, but it just prints 0. 0 also does 
not look very much like a valid value at all, or does it?

These are the commands used to build the modules (taken from the .*.cmd 
files):

// for the main module file:

I have no idea why those commands should lead to a file with broken 
relocations. Please help me...
