how to keep 2.4 and 2.6 kernels simultaneously

["J.S.Sahambi" <jsahambi@iitg.ernet.in>]

I am using Debian/unstable and recently instlaled kernel 2.6.6. Now on 
my system I have three kernels, viz., 2.4.20-bf2.4, 2.4.26-1-686 and 
2.6.6-1-686.

The problem is that 2.4 and 2.6 kernels have different set of modules to 
load, for example for usb 2.4 uses the module usb-uhci.o but 2.6 uses 
uhci-hcd.ko. But the /etc/modules file not versioned!

So is there any method by which the system can load appropriate modules 
when booting with kernel 2.4 or 2.6? The problem is that there is only 
ONE /etc/modules for all kernels!!

Thanks
