Funnily enough it's only KDE3 that doesn't accept my self-compiled kernels. With Gnome I can suspend and hibernate from the System menu while KDE3 doesn't offer me any option to do so. This means there must be something compiled into these kernels, or some option ticked or not ticked, that makes KDE3 realize it's capable of suspending and hibernating. I'll try the wireless module next. Could you tell me what exactly is different about a realtime kernel compared to a non-realtime kernel? Is it just the scheduling?
