Okay. I made some changes (I blatted about it before hand I think) which
caused selection of variable to occur as a default, modulo (cough) errors
in setting variable or already known 'fixed' block device (either by quirk
or by density code detection). I'll finish the second step and quirk to
FIXED a number of devices that really are known to be FIXED only.
Apparently too many of these devices say "oh sure, we do variable" when in
fact they don't.
