I guess it's in the 'might work but no guarantees department'.

Having had untold grief with a VL bus machine when I was conforming to the
spec, my instinct would be no to try it on, or at least to give up fast if
it shows signs of trouble.

Go for it. The PC architecture is far superior though prhaps compromised by
the mixing of VL and PCI technology in your case. I would only buy new PCI
cards as your next machine will be PCI in all probability.
