If you think a little bit, I bet you could come up with a solution that
operates at cacheline-aligned granularity, something that would be _even
faster_ than simply fixing the code to do aligned accesses.

Cache aligned compression is unlikely to compress anything at all.
Compression algorithms are usually by definition unaligned.

Sure it's a bitstream, but that does not imply the impossibility of 
reading data in in an word-aligned manner.

Maybe cache-aligned is ambitious, because of resultant code bloat, but 
machine-int-aligned is doable and reasonable.
