Only under strace or also without it? On my system this is the situation. I 
assume it segfaults always.

I don't know if this is recommended in your case(I'm aware of it only for when 
you have actually that split on the host).

I remember that the distributed kernel uses exec-shield, and you must disable 
it; also, there is a thread starting from "[uml-devel] [bug] uml segfaults if 
forcing static link, 2.6.0-test11" on uml-devel, started by Ingo Molnar, with 
deep discussion about Exec-shield; you need also, probably, another fix in 
this message in this ML(it's of this Wednesday):

[uml-user] Re: [bug?] uml segfaults, 2.6.0-test11+uml-patch-2.6.0-test9-1
