Thank you. I am still awaiting new real 6000 SIV save files so I can't check how the registers compare. Looking at the PCI config space then both my 5500 and the real 6000 have ROM BAR present, but it's zero on your card + they have cfgSliLfbCtrl as 00000000 and with your card it's 021F0060, why?
dunno, maybe that issue could be related to a pci to pci-ex adapter or to a bios settings. i don't like such config (bridge behind bridge), i don't like xp os for that card either. if you want to make some comparison, let's do it on the same systems in win9x.
that register you mentioned changes from 00000000 to the new value after a 3d app run.
to be honest, there's no space for an improvisation, every single pin of vsa chips is wired the same way as on the original board
