NAK.
I'm afraid I have to reject this patch.

First, please don't enable DEBUG like this in common files.

Second, I asked you before to implement this similar like the initrd
location can be controlled using the "initrd_high" environment
variable (see my message Tue, 07 Aug 2007 21:21:19 +0200). AFAICT you
never replied to this.
