Let me try to clarify: T2's display driver consists of two components: an updated mxc_epdc_fb driver (with extension hooks) that likely is compiled into the T2 kernel; and (probably – I haven't seen it yet) a proprietary extension using those hooks that likely comes as a kernel module. The latter does not work without the former, because the extension hooks are missing. (That's also why I think Sony might be violating the GPL.)

It probably will not work at all?
I'd start by using the T1 kernel sources and replacing the T1 video driver with the T2 video driver (they're compatible). Alternatively, the T2 sources also appear to come with support for the T1 platform, so you could try compiling a T1 kernel from those.
With luck, the proprietary T2 module loads into the resulting kernel on the T1, but as I indicated in an earlier posting, there are various reasons why that might not work out.
