You are utterly mistaken. If the Desire is as locked down as you say it is then explain the fully functional CM 6.0 that runs on it including the custom kernel. Check out the XDA Desire forum for some details and then hopefully you can come back better informed. Also, AOSP builds for the Droid X are coming with custom kernels. I find if funny that below you posted a quote to try and make your point that custom kernels wont be happening but you tried to completely ignored half of the quote by bolding just what you wanted people to see. Here's the quote YOU posted with your bolding left in place, but I've added a second bold+italics of the relevant portion you should be paying attention to.
"So can we now install custom ROMs?
Yes, but you can't replace the kernel or boot image. But really, once you have access to /system, anything is possible. It will just take a little hackery ."
Also, this quote was written when the Droid X was first released and they were just starting to get root access. Since then, a lot more progress has been made using a "little hackery."
Please stop posting FUD and misleading quotes. It was bad enough you couldn't even attempt to defend your initial post that cyanogen mod phone support was dwindling after I pointed out it had more that tripled in # of phones over the last few months.
You simply don't know enough. End of story.
