MD ROOT and image size limitation (makes kernel panic)

[rank1seeker at gmail.com]

I have a 4 GB or ram, so why kernel panic with my MD ROOT, if larger then 
~40 MB?
I've tried to split up root in 20MB image and usr in 160 MB
Via loader.conf root becomes md0 and usr md1 and panic occurs even when 
they are split

I had to get rid of md1, to be able to boot with md0 as a root.

What exactly imposes limitation, inside kernel's code to SIZE of an image?
My hardware definatelly isn't ...

Is this different on amd64?
I've tested this, only with i386.
