I was quite busy these last days but finally was able to continue the tests on my VAIO.
I tried both versions of DSDT.aml you sent me (v1 and v2) but the results are similar to art.sormy's, that is:
MSRDumper.kext: no P states at all
DPCIManager: P states vary as (7, 8, 9, 10, 11, 13) according to the processor load (7=idle, 13=heavy work)
Also, AppleLPC.kext does not load.
You are right, my 88e8057 didn't work. It's just shown in system as available and shown in ifconfig.
Try this one kext http://www.insanelym...e8056-108-1085/
Got the same results with this one: it doesn't work, doesn't detect the network cable.
One of solutions is to buy sony laptop compatible WLAN card ($20-30) which is also compatible with os x (like mine, for example, with broadcom bluetooth and atheros wireless).
Also you can buy usb ethernet adapter ($10) or usb wireless adapter ($10) but they will eats usb slots.
What is the exact model of your WLAN card? Is it the stock one or did you replace it? Does it work on OSX out of the box? I'd rather buy a WLAN card as long as it is 100% compatible.
Regarding your touchpad's issues, try this modified version of VoodooPS2:
This one still have minor issues but is by far the best one I found (anyways, my VAIO touchpad is crappy even on Windows). You should be able to tweak it on Trackpad (System Preferences) wich is quite nice.
Did you manage to fix the "About this Mac" bug?
Finally, can you share your Clover's config.plist? I think I messed up mine because the power button is not working any more
