Can you make it work on this GPU with local display (BIOS or UEFI)

IOMMU Group 1 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09)

That would be challenging since I don't have a sandy bridge exact device. Even for just basic display, the driver needs to go into a different code path for every minor device revision and display interface type. It's almost impossible to get something running without testing on the exact device combination.

On the other hand, doesn't pre-skylake iGPUs have their own VBIOS? Maybe you can just dump the official one and use it?
