Thanks, figured it out just after you posted. The PDANet drivers were the trick, in #3 below (don't need to actually run the installation in this case).
You'd think after 1.5 years of playing/hacking/unhacking/fixing and refixing the N1 I'd know how this is supposed to work.
A couple of comments, since some tutorials are based on older installations.
1. Installing android sdk. I went through a crapload of unnecessary trouble in trying to reinstall these, thinking that the usb drivers, adb, and fastboot needed to be updated. NO.
1a. In fact, in trying to reinstall the android sdk, you have to install the Java SDK. THEN, with the latest revision, R15, FASTBOOT IS MISSING! Need to pull that from a r13 zip.
2. You need the CORRECT samsung drivers. The ones mentioned above are the correct ones. I installed some limited half-ass versions which did not do the job.
3. You need FASTBOOT drivers. These were found from this post http://forum.xda-developers.com/show...44&postcount=1
(PDAnet x86 and x64 which are the fastboot drivers plus android sdk drivers)
The #2 drivers let ADB see it when ICS is running, #3 (and probably #2 too) are needed while in fastboot. To get #3 installed, I had to go to device manager in Win7, hit update driver (next to the error exclamation mark device), and direct to these files.
That is all <whew!>
