Not sure if this is related, but I've been fetching kernels from the Ubuntu Kernel PPA before previewing Ubuntu Netbook and later Kubuntu Natty on my ASUS UL30A.
The 2.6.38 kernels have had broken suspend/resume from the get-go, but versions since -4 have also had various degrees of broken Fn keys, i.e. broken ACPI support for my model. 2.6.38-3 works with Fn keys, 2.6.38-4 and up to the current -8 do not. ATM, with -8, the broken keys are isolated to brightness up/down which, with acpi_listen running, will be logged *extremely slowly* (like once every 20 or 30 seconds) and block the queue for any other buttons being pressed (like sound up/down). Also, no KDE overlays will be shown for the brightness keys, and no change in brightness will take place. Here's me pressing keys: daniel@daniel:~$ acpi_listen video LCDD 00000086 00000000 video LCDD 00000087 00000000 video LCDD 00000086 00000000 video LCDD 00000087 00000000 hotkey ATKD 00000030 00000000 hotkey ATKD 00000031 00000000 hotkey ATKD 00000030 00000001 hotkey ATKD 00000031 00000001 hotkey ATKD 00000030 00000002 hotkey ATKD 00000031 00000002 hotkey ATKD 00000031 00000003 ... The first ones are the brightness keys (took well over a minute for those four lines to appear), the rest are volume keys. I don't know if it's related to suspend/resume not working, but the issues arose simultaneously, and both are ACPI stuff, so I'm guessing they are :) Also, if this is unrelated to the OT, I'll back off :) Let me know if I can supply any useful output from somewhere. If nothing else, I think these might be of interest: daniel@daniel:~$ dmesg | grep -i asus [ 0.000000] DMI: ASUSTeK Computer Inc.
