Yup...
BTW, I've got a version of my u430 repo working that uses no patched DSDT/SSDTs... All patching/injection is done via Clover hotpatching, Abritrary injection, and a small SSDT. It is pretty cool as you don't have the ACPI patching process to go through, and you can update hardware, BIOS settings, BIOS version, etc. without re-patching. It simplifies the process a fair bit and will probably lead to less errors.
I may try the same with the y50 if someone is willing to test. We'll see as I get into it if there are any complications above what I saw with the u430.
Unfortunately, I ran into a lot of bugs in Clover in using these features.... and... I fixed them all, but they are not in the current build, so I'll wait until Slice integrates my fixes before putting it out for anyone else.
It took a *very long day* to put together. I suspect less for the next laptop...
This is just a heads up...
