Sure I'm insterested in compiling the driver to RPM and making it 
available to others.
I've tested the driver today (by connecting to the available access 
point) briefly and it didn't display any problems in functioning.
Now, according to the news clipping from computerworld.com, by 
installing this, one would still use the proprietary Broadcom firmware, 
which, I suppose, comes along with the driver released by Broadcom at:

http://www.broadcom.com/support/802.11/linux_sta.php

Also, according to the Broadcom's README, all other "firmware kernel 
modules" have to be removed (or blacklisted) from kernel before 
installing this.

I'm also willing of doing this, though, I am going to need some guidance 
in order for this not to take too long, since I've never done driver 
packaging before.

A few questions for start:

Ok, to build an rpm I need a spec file - this comes as a condition for 
packaging anything as RPM, right? Now, the only way to do everything 
else (i.e. blacklisting unwanted firmware files, importing kernel 
module, assigning modules to the devices ...) that I can think of, is 
via Bash script, or not?
