Yes, there was a segv problem with 2.4.17-10um, but Jeff provided a
solution for that.

We'll have to find out what Bill did differently, because I used the same
compiler (2.96 20000731), uml patch (2.4.17-5um), and perhaps the same
glibc (2.2.4) that he used to create the successful kernel included with
trinux-uml.

Hopefully, the mystery lies within the config, unless, there were some
additional alterations to the kernel code.
