Just installed this ROM. As a TEST I just did a dirty flash and installed it over 1.3 without full wipe and.... it WORKS!!! I know OP says full wipe but I was curious and SO FAR it's great, kept all my settings.
Just in case anyone wonders "what if"...
Love the ROM, great work! Love to see the toggles made it into the ROM, too! I'd like to throw my contributions in here, in hopes that they can come in handy for some:
If you DO NOT want the brightness slider, just install this:

If you DO WANT my little factory tethering hack which allows use of the built in hotspot (yes, unlimited users like me still can't use it after the FCC ruling and Verizon's loosening up on the tethering restrictions), install this:

If you like the AOSP/AOKP Android Keyboard, here is one I ripped from another ROM and made it into an installable ZIP for this ROM. It includes the Vol up/down cursor movement:

Credits go to lidroid and wanam for the awesome toggles and remf4i for the WhiteLightning ROM where I found the keyboard!
