This is all the acpi.sys files as far as i know, including the newest acpi.sys I have.

@Dietmar might have a newer one though.
@Dietmar
Can you run a debug on storport 8.0 beta 8102 to find the cause of this storport 7E BSOD?
(remember to restore original XP SP3 HAL and acpi.sys before running debug this)

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.
