Please don't do this.

*I* feel bad when I join a list for the sole purpose of asking a question, knowing that I'm going to unsubscribe as soon as I get my answer. But you won't even bother to join and sample the list traffic for a few days? I consider that very disrespectful... as though you consider us to be your personal tech support staff.

Nevertheless, I'll answer your question *and* CC you.

For a long time, my debian unstable laptop loaded wlan driver before wired
lan driver.. couple of weeks ago the order was reversed, wired lan drivers
were loaded before wlan.
The order that they're loaded in used to only matter because the names we assigned sequentially (eth0, eth1, etc.). Now, with udev, it appears that you can name your interfaces anything you want. You could name your wireless interface "my_favorite_eth", I suppose.

With this flexibility in naming the interfaces, the load order shouldn't matter anymore.

The best section I've found regarding renaming interfaces is at:
  http://www.reactivated.net/writing_udev_rules.html#example-iface

but I haven't had a chance to try it to see if it works.

And in fact my system now loads 2 different wlan drivers for the same card, orinoco_pci and hostap_pci.. how can I disable the other? I tried to add it to skip list of discover, but it didn't help..
Hmmm. This same question was asked on this very list earlier today. But then, you're not on the list, so you wouldn't know that.

One of the changes listed with the new udev packages reads:
+ /etc/hotplug/blacklist*: must be replaced by modprobe configuration directives.

Supposedly, you can prevent modprobe from loading a module by adding a file to /etc/modprobe.d which contains:

 alias drivername off

So, you could create a file like "/etc/modprobe.d/blockhostap" which contains:

  alias hostap_pci off

Is there tutorial/documents somewhere how loading of drivers is handled in
Debian nowadays?
I haven't seen one. However, it appears that udev handles all hot/cold-plugging now, and that it uses modprobe to actually do the loading.

So, udev handles finding the actual hardware and deciding which drivers need loading *AND* deciding what names they are assigned in /dev (read http://www.reactivated.net/writing_udev_rules.html). Modprobe handles actually loading the module and any other modules that it depends upon.
