The screenshots were made with an up to date (at that point of course)
8-CURRENT.
But I've tried to boot with the snapshot ISO, which boots fine.
Summary:
- the original problem: with a fresh pxeloader, the machine halts at
this point:

- 8-CURRENT, booting with an older pxeloader panics with this:

- the 640kB patch panics with this (8-CURRENT, older pxeloader):
http://people.fsn.hu/~bra/freebsd/20090107-freebsd-x4540/Screenshot-70.png
- with safe mode, I get this (8-CURRENT, older pxeloader, apparently no
NICs recognized):

- the December snapshot ISO with CD-ROM redirection boots fine, and it
seems the SMAP is OK too:

According to these, I think my problem is the pxeloader's inability to
boot on this machine. An older one can't boot because of the
memory-related difference, a newer one can not boot because of another
changes, happening in-between.
Somebody please help. :)
I don't know if there is a version, which can get to the loader prompt
AND initialize what need to be initialized correctly to overcome the
SMAP-panic.
