Took the Siyah flashable zip, extracted it (on my device, Android rocks!), replaced the respective file, repacked it, flashed it, worked.
Had to reboot the recovery twice though, before other zip flashes went through. Some permission problem or so after changing kernels I guess.
Hope you dont mind, V5 for the T (LT30p) as flashable zip: http://www.mediafire.com/?q07zuwu0nfigai4
