Re-post: Invalid module format and version magic complaints

Yes, the 2.6.10 kernel was compiled with gcc 3.2. Sometime thereafter, I 
upgraded my box to FC3 which includes gcc 3.4. And after that, I 
compiled hostap-driver.

Pursuing the theory that the compiler mismatch is causing the failure, 
is there an elegant workaround? Is there a way to disable the gcc 
version check? I would think that gcc-3.4 is a superset of gcc-3.2 and 
therefore should be backwards compatible...

Any thoughts?
