Unfortunately it's not as helpful as it became under Solaris 2.6+ :
Especially when someone hasn't use it for the long time. Actually it's pretty good:

Woo-hoo!
Hi Artyom,
I've just posted a patchset to lower the virtual memory allocation range - can you test with that patchset applied, plus my patch in http://www.openfirmware.info/pipermail/openbios/2013-April/007572.html means that you can still load kadb on your image?
If that works, I'll put together a patch to move the alignment rounding up behaviour in core OFMEM, as detailed in the specification.
ATB,
Mark.
