the graphical installer ( and maybe the cli installer also) is incorrectly identifying the builtin 1394 fire-wire port on at least soundblaster audigy cards as ethernet interface 0 (eth0) WORKAROUND: configure the GLI to use eth1 by unchecking the box "my ethernet controller is configured" and selecting eth1 from the dropdown box. FIX: possibly ask user if ethernet is through 1394 fire-wire connection before loading module or disable autoload for that module and put instructions into the installation handbook for enebling it EG: open a terminal and type modprobe eth1394
Eh, this isn't really an installer problem. The installer just looks at what interfaces are available when it launches. The modules are loaded at boot, long before the installer launches.
This is due to hotplug/coldplug "detecting" the firewire and loading the module. There really isn't anything (within reason) that we can do to resolve this and also to allow people to still use eth1394. Nowhere are we loading the module manually, so it is all done by the hardware detection.
