Broadcom Wireless adapters and kernel updates

[Temlakos]

Everyone:

Updating to the new kernel temporarily knocked out my wireless 
connectivity on my Dell Inspiron 1545.

That is, until I executed:

# modprobe b43

Or, since I am a member of "wheel":

$ sudo modprobe b43

A few seconds after I issued that command, wireless was enabled, and the 
connection I had long been using, re-activated itself.

Question: must I execute "modprobe xxx" with every kernel upgrade?

(By the way: it turns out that module "wl" is not necessary.)
