Hi Alex,
weird, I double-checked and I sent it to the address you replied from...

Will do so at the end of the week when (hopefully) 2.6.34-rc6 is out
and I have mor etime on my hands.
Could you a bit more explicit on how I could set a static power mode
via sysfs? I've never worked with sysfs before so some hints would be
greatly appreciated.

Thanks,
Klaus

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).
