Yes, did you actually read my mail?

You *really* think you're going to see a 440BX GART on ia32e ?
i810 ? i820 ? i830 ? etc. etc. I'd be *very* surprised if anything
but the current generation of ia32 chipsets gets used on ia32e.
It just doesn't make sense.

Without even looking at the code I'll bet you can shrink it
by at least 75%.
