Sorry, you're right.  I get lazy and just do ranges, in which case the lower
device number would be presented to the kernel first.

No.  The _first_ device number presented to the kernel becomes dasda.  The
second becomes dasdb.  It has nothing to do with what device numbers are
higher or lower than others.  You can have something like
dasd=0150,0149,0160,0123
That will give you:
0150 = dasda
0149 = dasdb
0160 = dasdc
0123 = dasdd

The lowest device number becomes dasda, the next dasdb, etc., so renaming
&
editing the hwcfg files would address the original scenario you described,
assuming the original DASD was also in order.  If the DASD is out of order
you'll have to use disk labels or persistent naming to resolve it.
