so heres what i did, i installed ideneb 10.5.6 on my desktop with voodoo kernel, then i used the 10.5.7 combo update from apple

is my installation running with vanilla kernel or is it still voodoo? and does my extensions folder still have the kexts i added when i first setup my computer? and does anyone know how to fix this bug where my computer reboots when i hit power-off in the apple menu my desktop is a dell inspirion 545s

thx
