Heh. This looks a *lot* like the user-mode hardware bringup/debugging
code I was writing in CMUCL during the last few years (for a now-PPoE).  ;-}
Lots of bit- & byte-field definitions, peek & poke stuff, utilities
to encode/pack/unpack/decode hardware register fields from/to readable
symbols, etc. The main obvious difference I noticed was that instead
of using SYS:%NUBUS-READ & SYS:%NUBUS-WRITE to peek/poke at the
hardware, my code did an MMAP of "/dev/mem" and then used CMUCL's
SYSTEM:SAP-REF-{8,16,32} and SETFs of same [wrapped within suitable
syntactic sugar, of course]. Fun stuff!
