is it offical rpm of kernel? if its so, try to change your language to english. some software doesnt work well if the system language isnt english.
u can try to install kernel from source. it will take much while. but u can choose what type of hardware and other options will be supported by kernel. so your kernel will be smaller, works better. i have fedore core 1 . i have compiled a costum kernel from source of kernel 2.6.4 for a while ago. but i must warn u that costum kernel compiling is hard. i think u can compile kernel by reading http://www.linuxquestions.org/questi...threadid=91503
.redhat and fedora are similiar
