this works great!  if i have serialnumbers in my ucoms :-(
out of 20 devices, i have 3 with serial numbers, leaving me
with 22 ucoms without a stable name (5 dual port devices.)

tempted to suggest we include something like this in src,
i just wish it could work better for me.  i just spent far
too long making them attach in the same order in a new
machine using hard coded kernel config.. oh well.

thanks!
