Hm, for that you don't have to recompile the kernel... unless you modified 
it before, of course. Just change your inittab and reboot.

No, shouldn't be needed either. You should get a string in dmesg like 
"linkstation: disarming the AVR watchdog:", and the watchdog should be 
off. Just take the original .dts, unmodified kernel sources and close 
enough to original (arch/powerpc/configs/linkstation_defconfig) .config 
and it should work.
