The 4.5 release will have several ACPI related changes, hopefully that won't be required.

All USB devices are supported... ugen(4) will always attach if no other driver claims the device, ugen(4) being the USB generic device, programs utilizing devel/libusb are essentially substitute drivers.

See, manual porting is required though..

This is a common compliant, OpenBSD doesn't support PXE.

Just imagine the x86 has a 32-bit address space.. physical and virtual..

2^32 is 4294967296 bytes, or 4GB.

If you install 4GB of memory you expect to have 4GB detected, unfortunately.. memory isn't the only thing that's mapped into physical address space, legacy I/O.. PCI devices.. AGP aperture.. all these things have priority over the real estate.

In reality, the modern x86 computers has a much larger physical address space.. 36-bit.. 48-bit.. but in the end the architecture is still fundamentally 32-bit, 32-bit register sizes.. 32-bit immediate operands.. etc.. So when you install 4GB of memory only a portion of that is mapped below 32-bit physical, the remainder is mapped above that.

Understanding the architecture you decide to use will make the experience much grater in the long run, I won't go into the details of paging or PXE.. but the overall point I'm trying to make is that OpenBSD properly detects what the BIOS has indicated available.
