I will try it, that is for sure.

I thought using "Install" section like used in official Fedoras package
and would be easiest/safest to implement. I saw %files section in some
spec file but could not find it at the moment.

In your /etc/rpm/macros.kmdl you used:
%kmdl_kernelsrcdir /lib/modules/%(uname -r)/build
so I tried yust replacing %(uname -r) with kernel version like:
pmbuild -ba --define "kmdl_kernelsrcdir
/lib/modules/2.6.18-92.1.22.el5/build" madwifi.spec
but I ws getting error:
make: *** /lib/module/2.6.18-92.1.22.el5/build: No such file or
directory. Stop.
My inital thought was I was doing something wrong, but now I figured it
out. There is a need for actual kernel to be installed, not just
kernel-devel. So far, only kernel module I have rebuild was kvm-kmod
that uses weak-updates technique and that kernel module is symlinked to
all installed modules. Even when I was passing him desired kernel
version I only needed kernel-devel package, not the kernel package also.
I just installed nedded kernel package and now passing kmdl_kernelsrcdir
works like expected.

I will have to print that and read it, but so far I am finding my way
around nicely (meaning I manage to find 90% of the problems on my own by
google-ing). I worked for several years as a Windows software developer,
last 8 years I am network admin and PC servicer.
Last 4 years I am using Linux (CentOS i386) more and more, I am almost
free of Windows now, and last month I decided to go all the way, give
back something to the community and start building and rebuilding all
necessary missing packages for CentOS, like freeworld (mp3,..) decoder
plugins for amarok, xine, then freeradius, etc...
Anyway, thanks for all the help. I will correct spec file, make it work
and test the trunk version.
