Dick, sorry about my newbie question: where can I find a mkinitrd source 
code to compile in my system?

I made the changes you suggest in the initrd script and it was not able 
to create the necessary devices at boot time...

version 5.0.8-1), but it still not working...

Any more ideas? When can I get the mkinitrd source code?
