hate to say it but not sure these older devices will handle GB as well as they do froyo.
if we see people have successfully run GB (and this does not mean works great except for.......) then reexamine this.
I totally agree with dmcleo, I do not believe that our OG Droids are built to handle GB. Many have tried and failed at successfully running the GB on the device. But again you two Sourcerer and magicians are an incredible team so you can probably do some 'magic' and get it to work.. but like i voted, I will say wait until 2.0 and based on the public opinion at that time move further!!
I will be there to test things for you (act as a guinea pig to test your modifications or a new ROM) if you need me!! So decide and do some MAGIC FOR US!!!!
