Say, could it also work to load the bootloader and the kernel from

     Cannot load bootp()bsd.rd.IP22.
     Problem reading elf structure at offset -2004877312.
     Unable to execute bootp()bsd.rd.IP22

     >> bootp()bootecoff bootp()bsd.rd.IP22
```
from [1].

Forget about this, it doesn't make sense as `irisboot` wants to load the kernel from disk, so using it like above won't work at all I think.
