Rebuilding and flashing the kernel on Nexus One 2.2 Dev Phone

[nature lover]

Hi everyone,

On the above phone, is there a proven procedure to obtain the correct
Android
kernel source files (FRF91), modify the kernel configuration, rebuild
it, and flash
the phone with it?

In addition to not knowing where to look for the matching source tree,
I was also
concerned about mismatch with the radio image, and other horror
stories about
dead phones, etc., that are related on the web regarding this!

Thanks in advance for any info on this.

regards
