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.
