GUYS!!!
IT'S BOOTING!!!

The proper way of booting is:

 · Taking the DOCKSTAR kernel, ripping out the IPSEC_NAT_T to 
   make it compile at all (why this module does not compile on 
   TARGET_ARCH=arm despite being enabled in this stock kernel I 
   do not know)

 · Loading resulting kernel.bin to address 0x1100000, which is 
   the address already defined in $addr_rd to normally load the 
   Linux ramdisk uInitrd
