Linux is the core of Android operating system. Android is the user interface built on top of it. Another UI built on top of Linux core and targeted to be used on mobile phones is MeeGo, which is developed by Intel (Nokia used to develop it too, before M$ corrupted them to switch to Windows Phone 7). The only phones I know that can run MeeGo are Nokia N900 and Nexus S.
I'm afraid you're probably confusing something. What did you mean by "dual-bootable (linux/droid)"?
With linux, the kernel includes more than you seem to realize. The drivers actually run in the kernel space
(which is unfortunate). This means closed proprietary hardware drivers could be packaged with the rest of what you're calling the kernel. This is actually what happens with Maemo, which runs on Nokia tablets. This enables the supplier to maintain control over the system. In the worst case, a supplier could even do some arbitrary encryption in one of the drivers, and then add to the user agreement that the platform cannot be manipulated or that you cannot run their competitors software, which would in effect use the DMCA to criminalize modifications. Having Android based on linux doesn't save us from that.
Google is a controlling, privacy-intruding, profit-driven corporate giant that profits from privacy intrusions. Although this is to a lesser extent than all google's competitors, an open-source GNU system has its merits, particularly with all the expectation about the rapidly growing trend to produce malware and spyware for smartphones. When a large majority of users are running Android - the single homogeneous system that everyone else runs, all with the same bugs to exploit, it becomes an attractive target both to hackers as well as corporations doing barely legal forms of data mining.
So back to my original question.. If a phone has the support of GNU developers who have written open drivers for all the hardware, freeing the device from corporate control, and thus the option of running "GNU linux" (e.g. Debian), or perhaps something more obscure like BSD, I would find that very favorable. And as I understand it, Debian runs on the Yuhua X2. Part of what makes that possible is having a hackable boot loader. If a phone has a locked down boot loader, I'm less interested. I'm not sure if that's a rampant problem or not.
In the end, I would like to have an idea of the hackibility of the different dual sim android models.
