It has been resolved by "ACPI: EC: revert msleep patch". Happily Len submitted it for mainline this week. You will also find it if you try the acpi-test git tree. We're all hoping 2.6.28 will be much improved in terms of reliable operation of different ECs :). > >> ** 2 - wireless: not to mention the fact that ath5k wasn't installed by default in ubuntu... >> wireless more or less works, but kernel log is full of backtraces. > > Well, that doesn't tell us much.

Probably the BIOS doesn't provide the normal support. You can try "modprobe pciehp pciehp_force=1", maybe it helps the kernel discover the devices. It worked for something else on my EeePC. But then it will reportedly disappear the ethernet controller. > > However, at the moment pciehp can cause delays of 10s of seconds during resume. Got, a SD card, and with help of pciehp it works almost perfectly in both slots. Almost, due to the fact that R/O switch is ignored. (Just as I expected, a s/w switch, couldn't they think more, and include a hardware switch?) On my main acer R/O switch works. However I have to use pciehp_force=1, I understand that probably acpi tables are broken, but could you add a workaround (dmi quirk?) Also, there is a acpiphp driver, which doesn't work here. pciehp is supposed to support so called native mode, don't yet know what it is, but here it still uses acpi. > >> ** 7 - opengl is broken, I tried running neverball in fullscreen, but it shows wrong/corrupted >> textures (compiz is running, and working well thought) I almost sure why this happens, opengl application is out of textures, I need to install gem enabled intel driver here, and see how it works.
