It is very easy to install a recovery: just flash a boot image to the RECOVERY partition with heimdall. You can get one from here, for example. These come with ADB and other means (zip) to flash the firmware.
The original boot partition may be be installed there as well (when PMOS sits on the SD card), to Dual boot the phone (has not been tested yet).
The soc is a member of the hawaii platform, so it's likely that the kernel or some other components can be reused on other devices from the same platform.
Copy-pasted from here, which is quite informative.
