Yes, If I disable ACPI (choice 2 on the beastie screen) it boots up 
fine, and that's the dmesg I posted. If I choose 1, then it just hands 
at the amrd0 line, and the ses0 line is never seen.

To disable ACPI correctly, then, I need only remove the option line in 
the kernel config file? What is the impact of running without? As far as 
I am aware it deals with power management. If my server is running in an 
air-conditioned room with redundant power supplies I shouldn't really be 
worried, correct?

What command will show me the current IRQ assignements? Just grepping 
for irq in the dmesg gives:

ioapic0 <Version 1.1> irqs 0-15 on motherboard
ioapic1 <Version 1.1> irqs 16-31 on motherboard
fxp0: <Intel 82559 Pro/100 Ethernet> port 0x1800-0x183f mem 
0xec900000-0xec9fffff,0xec801000-0xec801fff irq 18 at device 6.0 on pci0
amr0: <LSILogic MegaRAID 1.51> mem 0xf4000000-0xf7ffffff irq 20 at 
device 3.1 on pci4
atkbd0: <AT Keyboard> irq 1 on atkbdc0
psm0: <PS/2 Mouse> irq 12 on atkbdc0
fdc0: <Enhanced floppy controller> at port 0x3f0-0x3f5 irq 6 drq 2 on isa0
unknown: <PNP0f13> can't assign resources (irq)

Is there something more tailored than that? I scanned through sysctl but 
it doesn't look like they are listed therein.

Thanks,
David
