I'd say your best option would be to get a cheap Nvidia GT 710 or 730 and run it along side your RX580 in a lower PCIE slot.
Nvidia kept XP support up to GTX 980 whereas AMD dropped support around the R7 270.

I know this isn't related to ACPI, but I got my hands on some windows 10 private symbols and was wondering if you could use them to make an NDIS_emu extender using them like how you did for ntoskrnl?
@Dietmar
I noticed that ACPI 5112, which still has XP RSDT find function in it. also gives this 7E BSOD.
So I think I can narrow down the cause of the BSOD to either HalGetInterruptTargetInformation or HalGetMessageRoutingInfo in my HAL and not my ACPI table finding code.
@Dietmar
It seems like that's the case, I wonder why microsoft did it that way.
I'm going to go through vista beta acpi.sys and see which version is first to BSOD.
@George King
Can you run H2testw on it to confirm that it is legit? I'll be genuinely surprised if it is as these are usually scams.

If this is for the integrated motherboard GPU your only option in XP is a generic 2D only driver.

If it's for an nvidia or AMD card you can just get the drivers from their websites.
@user57
PCI DeviceID's are more useful than names when looking for drivers.
A PCI device might have the same name as another but be of a different hardware revision, which is why you should look for the DeviceID.
@OldSchool38
Have you got a pic of the BSOD?
There are community made drivers for XP out there for newer hardware, it should be possible to get it working.
@TheLeftOldComputer
Have you heard of XP Integral Edition?
It has an optional patch integrator script included with it that has community made patches that will resolve both your AHCI and ACPI issues.
@Dietmar
That's what I'm saying - add this code in to your HP DSDT table and then try and boot with it. leave out the lenovo tables.
