There is a way to get to the devices through the /devices tree.
I'm pretty sure that mapped io can be done through the devices in
/devices/iommu_at_f,e0000000/sbus_at_f,e0001000/sbusmem_at_0,0:slot0 in the
same way as through /dev/sbus0.

Of course, in solaris, the names of these directories will vary depending
upon the system type (because the addresses can change). You should be
able to puzzle out the correct devices from /devices tree and link them
to /dev/sbus* if that's what the software expects to see.

Of course, doing it wrong will crash you real good.
