Oh..i got it. I do have a working bios. Thank God. And I generated the
irq_tables.c using getpir. It still doesn't help.

One thing I did notice, it starts getting slow after mounting file
system.

You might have to adjust bus numbers. LinuxBIOS uses a different bus
enumeration than other boards on some systems

I would guess that means 'after I start /sbin/init'.

Can you do this:
boot with init=/bin/bash
which will get you an immediate shell prompt. Then do some looking around 
in that mode.

once you get up in init=/bin/bash mode, do an lspci.

I compare 2 output of linux command "pci"
from both Linuxbios booted linux and a regular bios booted linux. 
There are no IRQ assignments for lots of devices including IDE
controller, SMBUS.
Does linuxbios assign IRQs at all in the code?
