Indeed on the same machine and with same config? It's strange, I never saw 
this incompatibility, and I can't find bugs in the code able to produce this 
(with a quick look). Could you check on your part?

Which are them? It should be setuid root and executable...

However, since:

# perror 2
OS error code   2:  No such file or directory

Uml is saying it didn't find uml_net, or some of its libraries, not that 
there's a permission problem.

Possibly it's lying and printing the wrong code, dunno. But from current code:

arch/um/os-Linux/helper.c:helper_child
        execvp(argv[0], argv);
        errval = errno;
        printk("execvp of '%s' failed - errno = %d\n", argv[0], errno);

it seems not (that source file was somewhere else, guess in arch/um/kernel, 
until 2.6.14, but I think the content was the same).
