Blacklistiing modules

[Jar <jar@pcuf.fi>]

Hello

When using FC4 2.6.12, I have to put the following lines to the end of 
the /etc/hotplug/blacklist to get rid of loading orinoco_pci.

# a) Do NOT load orinoco_pci when we are using hostap driver
# b) Do NOT load hostap_pci or it's alias wlan0 defined in
#    /etc/modprobe.conf, let network service run it instead.
orinoco_pci
hostap_pci
wlan0

Now when I updated to FC4 2.6.14 this doesn't work any more. I have to 
delete orinoco_pci. Otherwise both hostap_pci and orinoco_pci are loaded 
at boot.

Intresiting thing is (according to dmesg) that the orinoco_pci is loaded 
first and then hostap_pci. Anyhow, finally lsmod shows that no orinoco* 
modules has been loaded. Who unloads them, does loading another module 
(hostap_pci) for same device cause that?

orinoco 0.15rc2 (David Gibson <hermes@gibson.dropbear.id.au>, Pavel 
Roskin <proski@gnu.org>, et al)
orinoco_pci 0.15rc2 (Pavel Roskin <proski@gnu.org>, David Gibson 
<hermes@gibson.dropbear.id.au> & Jean Tour

low) -> IRQ 11

wifi0: STA: id=0x1f v1.7.4
wifi0: Intersil Prism2.5 PCI: mem=0xdfbff000, irq\x11
wifi0: registered netdevice wlan0

Finally I have to delete orinoco_pci to get rid of it. That is not 
elegant way to handle this. Is there some other method than the delete 
method to handle this? Why the blacklisting doesn't work any more?

Is some feture missing from udev/hotplug that should handle this kind of 
  "many drivers to same hardware" dilemma?

o kernel-2.6.14-1.1644_FC4
o hotplug-2004_09_23-7
o udev-058-1.0.FC4.1

I am not suscribed to the list, so please cc.
