Well, I had the exact same problem yesterday (and it was
painful enough, for there are absolutely *no* comments on the
subject in the kernel Documentation directory, nor in modutils
documentation).

Here are some suggestions:

1 - include the current alias defaults in the depmod manpage
(I had to do strings /sbin/depmod to learn the defaults of
some things). If you think this is not a very good idea
(so you have to update the manpage all the time), could
you please consider giving depmod a new command line
option so that it dumps its current aliases/defaults so
the user can see what they are);

2 - include a sample of a configuration that works (I don't
know if the preferred thing here would be to include such
configuration in the kernel docs or in the modutils docs
or in both places). Here is what I'm using here at home
now:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#alias char-major-14 sb
alias sound-slot-0 sb
alias sound-service-0-0 sound
alias sound-service-0-1 opl3
alias sound-service-0-2 sb
alias sound-service-0-3 sound
alias sound-service-0-6 sound
alias synth0 adlib_card
options adlib_card io=0x388
options sb io=0x220 dma=1 irq=5 dma16=5 mpu_io=0x330

Are there any problems with the solution that I'm using?? I'd
like to understand these things more clearly...

Thanks in advance for your comments, Roger...
