it takes livna about a day or say to release the nvidia, ati, madwifi, ntfs, ndiswrapper and every other kernel module for a new kernel, so simply wait a day or two, then use yum to install nvidia and ntfs and all should be good, until then you can continue to use your old kernel and it'll work just fine. select it at the boot screen

Ooops... I goofed... seems I've broken video support in my old kernel by trying to fix it in my new.. So booting to the old kernel version dosen't help. This is what I get for being impatient.. LOL

Got my Cam and Ntfs going again, just had to re-make the cam module and re-install... as for the ntfs.. the creator's website had a FC4 kernel module in RPM format.. YAY...

Still no dice on the video card yet..

i have dowloaded kernel-2.6.15-1.1831_FC4.i686.rpm but as i tried to install it thru rpm -ivh blah blah
i got an error message " udev < 071-0.fc4.1 conflicts with 2.6.15-1.1831_FC4.i686". my current fc4 kernel is 2.6.11-1_fc4. plz tell how shud i upgrade this kernel to 2.6.15-1.1831_FC4.i686 ? plz explain in very simple steps but not thru yum as i dont have an internet connection. i have a wlan card ar5001x for which i m finding no kernel module of madwifi or ndiswrapper in all the sites and ftps.thats y i want to upgrade to 2.6.15-1.1831_FC4.i686 kernel for which i found wlan drivers of madwifi and ndiswrapper.

You need to update udev to the latest version (udev-071-0.FC4.3) before you can update the kernel.

i have installed kernel 2.6.15-1.1831_fc4 and i have found wlan drivers. but there is one problem.
