I can confirm that PTLsim userspace 32bit builds and works fine for
my netbook installation which consists of:

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=9.10
DISTRIB_CODENAME=karmic
DISTRIB_DESCRIPTION="Ubuntu 9.10"
and
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS"

$ g++ -v
Target: i486-linux-gnu
gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9)
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)

Running ./ptlsim -core ooo -- /bin/ls works as expected.

Like I mentioned earlier, I have had issues under FC11 with PTLsim not
doing anything. Maybe sudo would work on those machines?
