  yes, it's an ethernet switch. the four adsl lines will be connected to one
machine and used in a load balancing scheme, but that? another story. we're
connecting the 4 lines to one nic due to hardware limitations.

  I need to run pppoe on these lines to get the service.

  it's not my problem. I should have ommited that line.

  not everything is money. now I'm plain wondering if this could work or not.

  I have no such file here, not even in the whole /proc tree. kernel version
is 2.6.15-1-686 from debian etch.

Ah... do you know if you are even using the kernel-assisted pppoe?  I
assume that is not the case.

  I really don't know. I don't see any loaded module except these:

$ lsmod
Module                  Size  Used by
ppp_deflate             5664  0
zlib_deflate           20536  1 ppp_deflate
bsd_comp                5376  0
ppp_async               9952  4
crc_ccitt               1952  1 ppp_async
ppp_generic            25844  19 ppp_deflate,bsd_comp,ppp_async
slhc                    6240  1 ppp_generic

The answer is... no.

The only PPPoE code in the picture is the plugin.
