First thing: don't mail me privately. I feel compelled to answer in this case, 
and I don't like that, both because I have other things to do and because I 
have more important and better things to do.

I try to answer to all mails if possible, but I want to retain the freedom to 
change this choice, whenever I need or I want.

Said that, since I'm still kind:

Beyond other reasons, DevFS code is not safe to use.

I believe that udev should create /dev/ubd0 by itself - indeed, it will create 
nodes only for passed in drives.

At least, this will happen with recent UML kernels (I think that 2.6.13
