Ha! I'm in luck!
Just to demonstrate the work, I re-used portions of the hack by Dexter_nlb to load Tenfar's CWM based recovery.
remount the /system read write (terminal emulator or adb or whatever), copy the original one to /system/bin/charge_only_mode.bin replace /system/bin/charge_only_mode with the one in the package(which is a shell script). Create an empty file named 'recovery_mode' in the root directory of the sdcard if you want to boot into the recovery.
Power off the phone and then plug in the AC adapter( NOT the usb on your PC, or it will boot the android os). The recovery should show up.
So far I don't think the mod is worth much, but I guess it would be handy when android refused to boot and we can't get into the recovery using Tenfar's bootstrap app.
