Interesting. I was sure TiVoScripts wouldn't work with a Series 1. In any case, it sets 'upgradesoftware=false', which is probably why the software upgrade isn't installed.
As far as fixing it... Maybe if you removed the monte and used a kernel that had the initrd neutered... I hesitate to suggest anything definite. Are you sure you used TiVoScripts (aka Sleeper's iso)?
There's a difference between needing help, and just being plain ole' lazy.
