kernel modules

[Eric Tanguy]

I just update kernel to 2.6.18-1.2868.fc6. Usually after this i have to
recompile my wlan driver rt2500 but this time i found the driver already
installed without doing anything : 
/lib/modules/2.6.18-1.2849.fc6/extra/rt2500.ko
/lib/modules/2.6.18-1.2868.fc6/weak-updates/rt2500.ko

Is this kernel magic ?

Thanks

Eric
