I did a make dep, make, make modules and make modules_install.

Nope, will check that tonight

I hope the depmod -a will fix things. Normally I am very happy with the
standard kernels so I don't compile them a lot. Should check the
kernel-HOWTO a lot more often I guess :-)

Yes it seems lots simpler with less possibilities. For some applications
though all the options are overkill and all one needs is to limit the
(overall) bandwidth to avoid large bills from providers not using flat-fee
pricing :-)
Anyway, thanks for the tip. I will keep you posted.
