Yes, PAE is for what we call in FreeBSD land i386.

Now, to the rest.
I recently investigated this topic myself, so I can share what I learned.
The first thing you'd want to have is SMAP information.
You can get it at the loader prompt with 'smap' command.
It is also reported by kernel during a verbose boot, but it is only printed to
console; it is not saved to dmesg, because it is printed before msgbuf is
created.
Example of how SMAP information looks:
SMAP type=01 base= end=0009f800
SMAP type=02 base=000f end=0010
SMAP type=02 base=fec0 end=0001
SMAP type=02 base=e000 end=f000
SMAP type=02 base=0009f800 end=000a
SMAP type=02 base=bfdf end=bfe0
SMAP type=01 base=0010 end=bfde
SMAP type=03 base=bfde3000 end=bfdf
SMAP type=04 base=bfde end=bfde3000
SMAP type=01 base=0001 end=00013000
Type 1 ('01') is memory ranges free for OS use.
Note that the ranges could be unsorted.
SMAP would give you an idea what is free for OS use and what is taken away for
BIOS and hardware needs. Also note that what's reported as avail memory is
smaller than sum of sizes of all unreserved regions. Some space is taken away
by FreeBSD virtual memory code to store some core page/memory management
information (~3%). Memory used by kernel and preloaded modules is also not
included into avail memory.
If you discover that your system reserves, in your opinion, too much memory,
then consider the following things.
1. Some memory might be allocated as video adapter's aperture and/or video
adapter's memory in case of some integrated graphics solutions.
2. Some memory addresses below 4GB are used for MMIO (memory mapped
input/output) - accessing those addresses is actually communicating with some
hardware rather than accessing DRAM. Some hardware+firmware combinations can
hoist (or remap) DRAM that corresponds to such an address range to a different
address range above 4G. If you examine last line of my sample SMAP output, then
you'll see that there is 756MB of type 01 RAM above 4GB and that machine has
exactly 4GB of DRAM installed - this is MMIO range 0xd000-0x1
hoisted to 0x1-0x13000.
If your hardware doesn't support that option, then too bad - the memory is
overshadowed by MMIO and is effectively lost.
Sometimes hoisting option (under whatever name) has to be explicitly set in BIOS
configuration.
Thanks for the explanation!
That's about all.
I am curious as to what you would discover about your system - please share
with us.
I'd like to, but how do I get this information out of my box? There is
no serial line. The only way I know is getting a screen shot. Do you
know another way?
Unfortunately I do not have a docking station, there I guess I'd have a
serial line.
Also, sorry for the delay, I had to upgrade the bios in hope that the
em0 is recognized properly, but no chance:
em0: Intel(R) PRO/1000 Network Connection 7.0.5 port 0x3000-0x301f mem
0xee00-0xee01 irq 16 at device 0.0 on pci2
em0: attempting to allocate 1 MSI vectors (1 supported)
msi: routing MSI IRQ 256 to local APIC 0 vector 49
em0: using IRQ 256 for MSI

Thanks again!
