My experience is that printk's generally don't show up on xterms or konsoles. They will usually show up only on the console when you're not in X, and even then the priority of the message might have to be fairly high to actually get it to print on the console as opposed to only being logged. Check your kernel logs to find out if the message printed out there... John - Kernelnewbies: Help each other learn about the Linux kernel.
