PAE kernel problem on Dell PowerEdge 2950

I have a couple of new Dell PowerEdge 2950 with 16GB RAM and I found
the following issue when trying to install FreeBSD.

FreeBSD i386 6.4_RELENG

8 GB RAM: OK except "acpi_alloc_makeop_handler: can't alloc wake
	  memory" corrected with PR 120515

16GB RAM: panic: "pmap_mapdev: could'n allocate kernel vistual memory"
	  when loading miibus

32GB RAM: panic as soon as the kernel loads, cannot read the error
	  message (several pages)

FreeBSD i386 7.1

Plain distribution, I have not yet upgraded to RELENG.

It reports for each CPU, on GENERIC and PAE kernel:

    cpu0: <ACPI CPU> on acpi0
    est0: <Enhanced SpeedStep Frequency Control> on cpu0
    est: CPU supports Enhanced Speedstep, but is not recognized.
    est: cpu_vendor GenuineIntel, msr 471b471b0600471b



32GB RAM: panic as soon as the kernel loads

I got the 32GB RAM by combining the memory from both servers.

I'd prefer using legacy kernel (6.4) but I beleive 7.1 is OK too.

One of the server will not be installed for a while and I could run
test on it if I am directed what to doo.

I can repost to a more appropriate list if I am told what list would
be the best.
