Unfortunately in German there is a paper that describes 
an environment to port the Linux SCSI driver to L4:

http://os.inf.tu-dresden.de/papers_ps/l4scsi.ps

The source may be found at our CVS server.

In DROPS there is a Resource Manager (RMGR) that should control
all hardware resources needed by L4 tasks (physical memory,
hardware interrupts, I/O-ports). Until now I/O ports are not
implemented yet.
