Thanks for trying it.  It was the other big change besides the
resource allocator since the working log.

I used coreboot v2 and it doesn't fail.  Buildrom makes it easy to
switch between the two.  You just have to

svn up work/openbios/svn

to get the latest instead of Rev 186, after you've configured it to
use openbios.

I still get all the

Cannot manage 'PCI host bridge' PCI device type 'pci':
 8086 1237 (6 0 0)
Cannot manage 'ISA bridge' PCI device type 'pci':
 8086 7000 (6 1 0)

Cannot manage 'VGA controller' PCI device type 'display':

Messages, but then I get:

Welcome to OpenBIOS v1.0RC1 built on Jan 27 2009 19:55
  Type 'help' for detailed information

[x86] Booting default not supported.

Can you enable more debugging and/or figure out what is being accessed
at the failure?  I'll help from the coreboot side if I can.

Thanks,
