Flashing a T700 on Linux

First off, greetings, all. This is my first SE, having been a seasoned Nokia user for over twenty years.
I really like this phone, though a few issues I am having have prompted me to reflash.

The problem I am encountering is in locating some software to perform said task in Linux. (Gentoo 2.6.31)

Forgive me if it is on these forums, although I am unable to locate.

My question is: Is there any software I have available to me. Some source code would be nice, but a binary blob would obviously also work.

Keeping my fingers crossed here.

Thanks, in anticipation.
