Sounds like you've got some troubleshooting to do.
You say that it "hangs during boot" ... yet it "boots past single user mode" (?). You also say "a remote location (that I can't get to)" ... yet apparently *somebody* can insert a "SLAX live CD".
You *didn't* say if this was a new install (if so - perhaps it's time to *re*install), or what specific error message you're seeing (notably, the *last* messages in "dmesg" before the "hang").
Worst case (assuming you can't boot to a state that gives you *any* kind of logon: either direct, or telnet/ssh):
a) boot from a different OS (a live CD, for example),
b) manually "mount" your hard disk,
... and ...
c) look at the errors in the logs.
