Ubuntu :: 10.04 - BIOS Does Not Support CPU Scaling

I've been trying to get lucid to work on my gateway netbook. The major problem I've seen is that it would overheat (to about 63 C or a little higher, and then the display would go crazy and crash. My BIOS doesn't support cpu scaling. Somewhere in a google search, someone mentioned the 2.6.34 kernel. I had no ideal what I was doing, and I installed this kernel. (could not install headers -- a dependency issue I didn't understand). Tried it, and it booted.

Saw some errors, like timer or something not found and something about a soft reset. However, it boots, and it works, and the temperature is much better (at least for the last 42 minutes: I've not been able to run it that long before). Are those errors likely to cause problems? Are there any issues I should be aware of using a non-standard kernel like this? I am dual booting with 9.10, which works well, and all my serious work is on the 9.10 partitions.

As I write, temp is still at 56, but I am getting some intermittent display problems. Should I give up on lucid?
