This is not correct. If you just scroll  down  the  page  you  listed
yoursself,   then   you   should   easily  find  the  section  titled
"RouterBOARD 500 GNU/Linux support files" which includes  a  link  to
"Patch for Linux 2.4.29 kernel".

Download the patch, download the corresponding  kernel  source  tree,
apply  patch,  copy  "config.mipsel"  to  ".config"  to get a default
configuration, build the kernel, download it, run it.

So far I haven't been able to find out how to pass  kernel  arguments
with their boot loader, so you may have to hack rc32434/rb500/prom.c

I used the mips_4KCle packages of the ELDK to build the kernel and to
provide a root filesystem over NFS - this worked fine. There are some
problems (like not being able to switch the CPU clock and NAND  flash
support not working at all), but it boots and runs.

Best regards,
