Sorry, you have been to fast... I've already prepared a solution for this: (see attached diff)

The driver asix.c has been fixed in a similar way some time ago:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-
2.6.git;a=commitdiff;h=51bf2976b55d07f9daae9697a0a3ac9f58abcedc

I've tested this change with 2.6.17 and 2.6.23 on a SH-4. The patch should compile with 
the current version. Could you please apply this for me? I've no routine in preparing 
patches for lkml.

Thanks
Christian Eggers
