Oh, now that you've mentioned it, I've noticed I've been using sysfs for years in my customized fan-script for my machine without knowing^^
Thanks for clearing that up!
PS: On another note, is the KMS PM code supposed to work with r100 chips (Mobility 7500)? I've tried it yesterday and the machine (IBM T40) hardlocks when loading GDM (Ubuntu 10.04, 2.6.34-rc5 without any additional patches).
In theory, although I haven't had time to test older chips much yet.

I'll test the new patches ith .34-rc6 on the weekend too and will report back. Whenever you need a testcase for ancient r100 hardware feel free to mail me (I'll be reading the list too)
