Punching the assembler snippet into a simulator, it runs as expected,
generating a pseudo-random number sequence that doesn't repeat the seed
until the 255th byte - so, allowing for the 8192-vs.8196 issue that's
already been covered, the problem must be somewhere else.

(Interesting notion to pre-generate a table of values and cycle through
them; it wouldn't be practical for a larger LFSR size, but for a basic
8-bit one it's certainly a nice way to get fast random numbers!)
