新编译的内核不能adsl上网，麻烦各位帮忙看看

rtdebian

错误信息如下：
debian:/# pon dsl-provider
/usr/sbin/pppd: This system lacks kernel support for PPP. This could be because
the PPP kernel module could not be loaded, or because PPP was not
included in the kernel configuration. If PPP was included as a
module, try `/sbin/modprobe -v ppp'. If that fails, check that
ppp.o exists in /lib/modules/`uname -r`/net.
See README.linux file in the ppp distribution for more details.

查看/lib/modules,还真的没发现ppp.o，但是我在配置的时候，已经选择了isdn，为什么会这样呢？希望兄弟们帮我分析一下。
配置如下：
#
# ISDN subsystem
#
CONFIG_ISDN=m
CONFIG_ISDN_BOOL=y
CONFIG_ISDN_PPP=y
# CONFIG_IPPP_FILTER is not set
CONFIG_ISDN_PPP_VJ=y
CONFIG_ISDN_MPP=y
CONFIG_ISDN_PPP_BSDCOMP=m
# CONFIG_ISDN_AUDIO is not set

#
# ISDN feature submodules
#
# CONFIG_ISDN_DRV_LOOP is not set
# CONFIG_ISDN_DIVERSION is not set

#

ADSL 与ISDN有何关系列呢？

应该打开PPP中的
Device Drivers --->
  Networking support --->
    <*> PPP (point-to-point protocol) support
    <*>   PPP support for async serial ports
    <*>   PPP support for sync tty ports
    <*>   PPP over Ethernet
吧？另外试试rp-pppoe？
ISDN似乎没有必要

注意下面的帮助，如果说If not sure say Y就选是了

需要ppp，
isdn一点关系都没有
