Don't know about the problems above, but this last is a "stuck pty" - what
pty did telnet report before it froze up? I've seen these all too frequently
in 1.3s and 2.0.0 kernels. Does anyone know how to unstick these besides
a re-boot? I vaguely remember something about echo'ing into the /proc
file system... ?

Currently I just force some process to hang on the port and just leave it
until the next reboot. You should then be able to get in on the next pty
(unless/until it freezes).
