Ok, I've built and installed the new kernel with the patch applied and it works! It responds snappier to mouse movements and I played a full-screen youtube video that seemed smoother to me. Not a very scientific measurement, I know. I downloaded and built interbench (Con Kolivas' tool to attempt to measure interactivity). The results don't mean anything until I test the other kernels for comparison.
I've only noticed one glitch. My 3g usb wireless dongle doesn't work. (The driver may not have been built). I have a few things to investigate before I can make a guess as to why. If I modprobe hso, the driver does not exist. If I try to build the driver, it errors out. This driver is for an earlier kernel and, in fact, the driver was supposed to be in the 2.6.27 mainline.
The good news is my atheros wifi works perfectly.
I used the .config from /proc/config when the 18.104.22.168.tex5 was running. I am assuming it picked up the selections and only asked questions for new or changed options, but I am not sure. I selected all of the defaults from there. I had to 'make modules_install install' and then 'make install' put the kernel in /usr/src and added a correct reference in /boot/grub/menu.lst.
I'll report my findings from interbench and post back later. When I am completely satisfied, I will try to make a source rpm. I will probably need help with that as well. Thanks.
