I'll help as much as I can.  Just tell me what you need to know.

I'm not clear myself here, and I think it is probably relevant.  In general 
terms the 2.6 kernel loads modules from modprobe.preload rather than 
modules.config, but I did note before I started to have this problem that the 
emu10k1 drivers for my card seem to be loaded from modules.conf.  Someone 
then said that I should add the lines

options snd-usb-audio index=0
options snd-emu10k1 index=1

but I'm not sure whether that goes in modules.conf or modprobe.preload.  
Apparently these lines are to deal with hotplugging.

Perhaps Killian could use generalities to clear up this for us?

I am discussing this problem on the Mandrake Expert list.  I suggest that you 
join us there.  You need to send a message to sympa linux-mandrake com with 
the subject line saying 'SUBSCRIBE	expert'

It's best to talk to experts on both sides of the equation.
