[Q] Flashing new ICS modem?

I have a question:
I'm presently runningthe Nocturnal Venum AOKP rom (which is awesome
I might add) but this question actually has impications on all the
ICS 4.03 & 4.04 roms. After Flashing the rom and whatever else you
flash through the EL26 CWM(5.027) based kernel and rebooting you
loose that CWM and must get CWM from the Play Store.
My question is this; Say I want to flash a new modem must I Odin
the EL26 kernel http://xdaforums.com/showthread.php?t=1514665
using the method per kbizzle and then flash new modem and reflash
ICS kernel? This is important to know as the only unrecoverable brick I
have manufactured is with the flashing that goes between gingerbread
based recovery to ICS rom and attenpting to go back. I admit I'm a 50
something year old noob with building pc's as my experience before
getting into the android game so I wont pretend I'm something I'm
not! I have flased better than 100 roms and am learning more with
each possible bricking roll of the dice flashing I do and I have
bricked my share. Is their a CWM in the works for flashing modems
and so on in the works? Any help will be greatly appreciated!

Flashing new ICS modem

OK cnstarz,
That's what I needed to know and appreciate your prompt response! You raise another question which is was using or wanting to use CWM for nandroid backup but as it wouldn't flash modem, the nandroid backup is also out of the question. I plan on using the rom I'm on now as a daily driver but like to try others out and know that I have to basically Odin back to gingerbread to either try another gingerbread rom or to do another ICS rom. So, my guess is I have no nandroid option or is there?
Again thanks for your help.
