Excluding dm-mirror does not boot my test system, adding it worked on, so at 
least dm-mirror should be included, but I have no more the test sytem now for 
a while so I cannot try to exclude modules one by one.

I think this is already handled by yaird since my patched yaird booted my 
system correctly.

So at least for a sempron64 with sid i386, using dmraid, my patched yaird, 
running two sata disks as a mirror (raid1) array on nv_sata/"nv_dmraid"  it 
worked.

Could someone ask upstream dmraid author to look at dmraid sys interface? 

In the specific, the partition directory in it are missing and each partition 
is treated a single device, so normal tools miss to find the proper device 
hierarchy.

I found a work-around for yaird but without a proper syfs interface I saw that 
at least lvm2 tools (e.g. pvcreate) did not recognize the array, hence it 
seems that I could not create lvm volumes. (Yes I was trying to test yaird 
lvm2 on dmraid... )
I saw that also evms tools and grub-install have problems. Grub is easy to 
tweak, but the other two.... I sincereley have no time now to mess with 
something bigger that the beautiful yaird.
