[coreboot] H8DME-2 woes, hints?

As a first time coreboot user, I thought that I should first try it out
on a supported board. That way I would learn the ropes a bit before even
thinking about doing something more challenging.
Naturally I am having troubles. I suspect that as a newbie I am probably
doing something stupid. But then I've heard that mb manufacturers like
to change things around without notice, so maybe I'm doing things right
and what was once a supported mb, no longer is.
The hardware:
SuperMicro H8DME-2.
Four 1Gbyte DDR2-667/533/400 Registered ECC SDRAM sticks from Crucial.
Two Quad-Core AMD 2378 2.4 GHz Processors.
Onboard video.
One SATA disk.
One PATA DVD-ROM reader.
NULL modem serial cable from COM1 to COM1 on another PC.
The details:
When booting coreboot, nothing happens for about 45 seconds.
Then the fans speed up to high and some messages start appearing
on the serial line. These messages print rather slowly (maybe
1 second/message). They are:
coreboot-4.0-r5521M Wed May 5 10:53:42 EDT 2010 starting...
*sysinfo range: [000cf000,000cf730]
bsp_apicid=00
Enabling routing table for node 00 done.
Enabling SMP settings
(0,1) link=00
At this point coreboot ceases to make forward progress. The
fans remain spinning at their highest settings. The VGA screen
is blank throughout.
I put some printk's in setup_smb2, the crashing routine. They show
that setup_temp_row is called by setup_smb2 but never returns.
Anyways, I've attached the entire build procedure I used to achieve
these results. Perhaps there is something in this sequence that I am
doing wrong??? And, what kind of luck have others had with recent
H8DME-2 boards?

Joe
