Sure. sid was designed to provide models as modular as integrated
circuits are. Conceptually, one replicates pieces that represent
unshared hardware (CPU, memory, whatever) to give them all distinct
names/types/connections. One challenge is configuring the non-hardware
modules: those parts that relate to debugging, program loading, host I/O,
scheduling. This can get complicated because of the number of degrees
of freedom. It is simpler for a homogenous SMP system, where almost
everything is shared.
The public sid/bsp/configrun-sid script doesn't know how to construct
such configurations automatically, but we have a newer C++-based
configuration generator written by Graydon Hoare that does know how.
If there is interest, we can try pushing it out to sourceware sooner
rather than later.
