Looks like a good start (see comments below)

Is your cpu id in model_6xx_init.c? I'm not seeing any attempt even at
cpu init in the LB boot log, and IIRC there should be something printed.
And if I'm reading the kernel boot log right, your model ID is 0x06a5,
which isn't currently in there and not added by your patch. I'll fire up
the mew-vm tomorrow and see if it has the same problem, the boot on that
board is slow but not that slow, I figured it was just my old 400MHz
celeron running over a serial connection.

Can you send lspci -xxx from linuxbios? I really can't see anything too
alarming in the boot logs, although I could be overlooking it. Can you
also try memtest86?
