Help with linux dual boot cfw, keyboard doesn't work :(

Hey guys! I'm in the need of some help, I just installed the linux dual boot custom firmware, went through all the steps, successfully installed petitboot (AFAIK.) My problem is when I boot into petitboot I can't select anything, my keyboard doesn't seem to work. I have tried a few keyboards and none work. I already burnt a disk and petitboot recognizes it :) but I'm unable to install because I can't use the keyboard. I have a phat ps3 model number CECHK (16MB flash.) I have no idea what's wrong :S Any help is appreciated!

I have the same problem
i make the firmware Rebug + otheros++ with ps3mfw
installed with these steps ( rebug.me ) all succesful ( i choose ps3 HDD )
my keyboard works on my pc and on my laptop
is works on XMB ps3 but is wont work in petitboot

plz can someone help us? we are so close:P thnx

( CECHH04 )
