OK, I've complied a 2.6.0 host with this (and only this) -A2 patch for
an SMP pentium III. The host is running debian unstable.

I also compiled a 2.4.23 uml kernel using uml-patch-2.4.22-7.bz2 and the
small ELF_PLAT_INIT fix.

Using a very simple root_fs (it basically only contains a busybox
/bin/sh and a statically compiled /bin/zsh4), the uml boots and detects
skas3 and /proc/mm on the host.

The problem is that on every process fork, I see $Subject appear one or
more times on the console, and subjectively the uml seems to be running
a little slowly. Is this normal?
