I found where it comes from : somebody patch ueagle-atm and broke it : 
http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=e7ccdfec087f02930c5cdc81143d4a045ae8d361

I have to investigate why this patch is need, but it is nice to see that 
the patch wasn't forwarded to the maintainers and I wasn't aware of it...
