GEOM_ELI with device crypto makes root unmountable

[Ari Sovijärvi]

Hi all!

I have a Sparc64 FreeBSD 7.1 system running on Fire V100 with root on a Gmirror 
device. I recently read about GELI and decided to encrypt one of the partitions 
on that machine. My kernel config is basically generic with quota being the 
only added option. The system worked perfectly fine, until I recompiled the 
kernel with the following options added (as instructed by the handbook):

device crypto
options GEOM_ELI

With those 2 options, the system completely skips detecting almost all of the 
hardware (including the HDD controller) and then fails as it can't find root. 
Apparently something is very wrong, but I can't figure out what's the cause. 
Any ideas?

Here's the dmesg up to the point where it can't find the root partition:
