Yeah I am running it with "pci=noacpi" when I use the laptop. Tried "acpi=noirq" just now and it does not boot. As for X, since I have 4 cores and 8 threads, 1 full thread registers as just 12% cpu used, and there was no fan noise, etc. I'd say that for me this indicates X is malfunctioning somehow under these settings (power management?), also most of the slowdown could have been visual lag (for example it was worse when moving windows and so on)
