kernel header mismatch, ixp400_eth.ko module crashed while inserting

[Sunny Jp]

Dear All,

       I am porting new linux 2.6.16.14 on IXP425 processor ,ADI COYOTE board.
       As Ethernet driver and access library v2.4 from intel supprot 2.6.16.X, i am going to build buildroot using 2.6.16.14 but the problem is i am unable to select kernel header for 2.6.16.X.

So i have compiled buildroot with kernel 2.4.16.14 and kernel header 2.6.22.10 and generate kernel and ramdisk image for that , but while running on board, it give error following errir while inserting ixp400_eth.ko module,
 

does this following error due to different version of kernel and kernel header or i am doing some other things wrong?
