When checking your kern.log, it can be seen that the amount of swap is 0!! So it seems you don't have swap partition or file mounted.
You may check it with "swapon -s", if nothing is returned it means you have to check why the swap is not mounted. You can check the last lines of /var/log/messages to get some info. Give a try to fix this first. Actually in my case the kernel uses "voluntary-preemtion" (it seems to be the default in the default generic kernel) and kaffeine seems to work better this way. I have compiled the kernel with "preemption" instead of "voluntary-preemption" and I get small troubles with the multimedia applications, so I went back to "voluntary-preemption" and I have no complaints. If you use full preemption, since the low priority processes need to be kicked out often from the processor, this means that the total performance will be little bit lower. Since your system has only 1 processor, and if you are interested in recompiling the kernel you can get the system a slightly smoother by recompiling the kernel with out SMP (Symetric Multiprocessing, enabled by default on the generic kernel). If you disable SMP then you need to enable "Local APIC support on uniprocessors" (which is just 2 or 3 lines below when using "sudo make menuconfig". I am running Linux in a external USB disk, so I have no possibilities of having DMA. But I noticed some improvements when the disk is swapping if I set SWAP_TOKEN_TIMEOUT=50 (or even 25) in the file thrash.c (which belongs to the kernel sources and usually in /usr/src/linux- source.../mm/), and then recompile the kernel. It seems that the swap does not work so well if you don't have DMA enabled. In normal cases this should not be needed, but if someone is running Ubuntu in an USB HD this may help. I have a 2GHz CPU and 1GB of memory, and the system is running even better than in dapper. I think if you fix the swap thing you will notice it also.
