So the first thing to do is, try taking a rescue disk, using its config 
(/proc/config.gz if you can't find it anywhere else), compiling your 
kernel for it, and using your kernel on someone else's disk.  A simple 
disk, like RIP, should work.  That way, you can check if your kernel 
works, if you can mount reiser4 (maybe on a ramdisk?), and you can try 
various modules and options to try and find your hard disk.
