David,

I'm not sure what hardware you are using.  In my case I have supermicro 
motherboards with dedicated IPMI ports.  I do need to do some BIOS setup 
for the console redirection.

Have you tried booting single user, without acpi, or one of the others?  If 
one of those boots, you may get some idea.  If not you might boot a live cd 
and check the crash dump.
