请教 linux启动自动加载程序的问题

我在使用make menuconfig 配置一些关于网络方面的驱动，在启动后串口打印信息如下：
loop: loaded (max 8 devices)
orinoco.c 0.13d (David Gibson <[email protected]> and others)
WL1100C-CF driver v0.1 developed by Strong Studio (embed.8800.org)
Detected Orinoco/Prism2 CF device at IO:0x4000000 to 0x400003F
eth1: failed to initialize firmware (err = -19)
eth1: Failed to register net device
PPP generic driver version 2.4.2
PPP Deflate Compression module registered
PPP BSD Compression module registered
No NAND device found!!!
Failed to scan nand!
上面是先将无线网卡驱动程序启动了，再启动ppp协议程序，我想先启动ppp协议再启动启动其他驱动，请问管理启动先后次序的文件是那个，怎么修改？
