Neither...try grep'ing around for uses of lp_flags.  I dug into this
last Dec/Jan...check the hackers digests from that time for any
relevent info.  At that time, only two bits in lp_flags were in use.
Don't know if any more are taken now or not.

Both lp_len and lp_offset should be the same, so if you take four bits
from lp_flags (and give two apiece to lp_len & lp_offset), that would
get you to a block size of 32k.

Now that there're timely src snapshots available, I'm going to try to
get back into coding (assuming the aix port still works. :)
