recently updated my kernel and that created two entries in lilo. i tried to remove linux_old and removed some kernel packages keeping linux-image-3.5.0-23.when i rebooted my computer, the menu remained. but my touchpad stopped working, tried fixing it by reinstalling the packages, but i found out that my wlan device is not working. neither i can mount cdrom nor use a fat32 pendrive. even my audio device is not working. can anyone name the package?
