I tested it with recent coreboot + filo-0.5 and I confirm that it
works. BUT I had to change 'linuxbios' -> 'coreboot' everywhere. The
fixed patch is attached.
Please, commit it. And big thanks to those who was taking time to help
me with my old motherboard, especially Uwe!

The following issues have been found. Regardless of which, I think,
the patch should be committed.

0. filo-0.5 can't find hda HDD: 'No drive detected on IDE channel 0'.
That is, I believe, because of bug in filo-0.5. The patch is attached
which fixes the problem for me. I've already posted it, and it got
some critique. Please reconsider it. If it may cause problems, explain
them to me.

1. PS/2 keyboard doesn't work. (USB keyboard does.) I'll try to
investigate it myself.

2. flashrom outputs: 'No EEPROM/flash device found'. It is probably
because of a locked flash device. People on IRC gave me some tips, so
I'll try to investigate it myself.

3. I have a PCI card which is a host controller for IEEE 1394 and USB.
When I boot with the standard BIOS, USB devices attached to it work.
When I boot with coreboot, and plug in a USB device, it doesn't work
and these messages appear:
	usb 1-4: new high speed USB device using ehci_hcd and address 3
	usb 1-4: device descriptor read/64, error -110
	usb 1-4: device descriptor read/64, error -110
	usb 1-4: new high speed USB device using ehci_hcd and address 4
	usb 1-4: device descriptor read/64, error -110
	usb 1-4: device descriptor read/64, error -110
	usb 1-4: new high speed USB device using ehci_hcd and address 5
	usb 1-4: device not accepting address 5, error -110
	usb 1-4: new high speed USB device using ehci_hcd and address 6
	usb 1-4: device not accepting address 6, error -110
Googling on it suggests that it is a PCI IRQ-related problem.

4. coreboot works with 'NVIDIA GeForce2 MX 400' video card (64 MB),
but hangs with older 'NVIDIA Riva TNT' (16 MB). With the latter
nothing is displayed and the computer hangs after 'entering emulator'.
With the standard BIOS both cards work. Here are pieces of logs
related to VGA:

NVIDIA GeForce2 MX 400 (64 MB):
	rom address for PCI: 01:00.0 = f9000000
	PCI Expansion ROM, signature 0xaa55, INIT size 0xcc00, data ptr 0x00f4
	PCI ROM Image, Vendor 10de, Device 0110,
	PCI ROM Image,  Class Code 030000, Code Type 00
	copying VGA ROM Image from 0xf9000000 to 0xc0000, 0xcc00 bytes
	entering emulator

NVIDIA Riva TNT (16 MB):
	rom address for PCI: 01:00.0 = f1000000
	PCI Expansion ROM, signature 0xaa55, INIT size 0x8000, data ptr 0x7623
	PCI ROM Image, Vendor 10de, Device 0020,
	PCI ROM Image,  Class Code 030000, Code Type 00
	copying VGA ROM Image from 0xf1000000 to 0xc0000, 0x8000 bytes
	entering emulator
