Red Hat 9 is Evil. . . .
I remember this horrible debate a long time ago where a lot of people were complaining about Red Hat and some other Linux distros backporting code into their distros. I haven't really seen the problem firsthand, as I was using Mandrake at the time.
I've been taking a linux course this week at work, Linux device drivers and all that fun stuff. Due to company infrastructure concerns, we're doing the old 2.4 kernel. So, we're use Red Hat 9. First, my laptop overheats if the processor runs at full power; it takes about an hour before it crashes. Hard. Red Hat 9/Linux 2.4 does not support CPU frequency scaling, so it runs my processor at full power until it crashes. Red Hat backported 2.5 code into Red Hat 9 and they backported the CPU frequency scaling code. Problem. When I enable that, the kernel does not compile. Bastards. Al, thanks for finding CPUSpeed. Unfortunately, the stock Red Hat 9 kernel does not this support built in and I can't build a kernel with that support in it.

Does your laptop use APM or ACPI? ACPI on 2.4 seemed pretty spotty, but someone rigged up a specific patch for my laptop model so it worked out well enough.
