Oops with belkin F5D6050 and 2.6.5 kernel

Hi,

I did succesfull run my belkin F5D6050 on my dreambox (linux sat 
receiver with powerPC processor) with 2.4 kernel. Now I am trying to use 
my belkin on the dreambox with 2.6.5 kernel and I get a kernel oops. I 
compiled driver version v0.12beta11 from CVS because the head version 
does not compile for 2.6.5 kernel. This hapens during insmod:

/wlan/lib > insmod usbdfu.ko
Using usbdfu.ko
/wlan/lib > insmod at76c503.ko
Using at76c503.ko
/wlan/lib > insmod at76c503-rfmd-acc.ko
Using at76c503-rfmd-acc.ko
Illegal instruction

I get an 'Illegal instruction'. With dmesg I can see the kernel oops:

Is there somebody that can help me to solve this kernel oops.

PS the kernel is tainted because the dreambox uses propriatry drivers, 
but I did compile the used kernel myself.
