I know bigmem is still in a state of flux and can be enabled by editing
machdep.c and compiling a custom kernel.
I also realise that it may or may not work on OpenBSD AMD64 due to the
absence of an iommu on non VT-d capable Intel systems, aside from the
AGP/PCI-e GART.
What's the best way to test and report this? (GNATS etc?) Is booting up
sufficient, or does it require extensive testing of memory transfers
from each device to above the 4GB line?
FWIW, with the latest kernel UHCI and AHC (specifically an Adaptec 29160
running in a 32 bit PCI slot) don't work on a 975X/Core2Quad system.
Once that's fixed the system boots. (iic also needs to be disabled, but
that's an issue specific to the D975XBX2 motherboard, not to bigmem).
