try the latest qemu in the SerialICE tree


It's already patched, and it has been updated more recently than the patch.

Sounds like SerialICE is depending on some initialization from the
vendor BIOS.  I guess an ugly way to test it would be to copy the
working configuration bits from lspci and hard code them into
SerialICE until you find what's wrong.

Like this ? E.g. this is what I found for ICH5's LPC_EN, offset address 0xe6:

00:1f.0 ISA bridge [0601]: Intel Corporation 82801EB/ER (ICH5/ICH5R) LPC Interface Bridge [8086:24d0] (rev 02):
// snip
e0: 00 00 00 80 00 00 08 14 33 22 11 00 00 00 67 45

pci_write_config16(PCI_ADDR(0, 0x1f, 0, 0xe6), 0x1408);

Attached the mainboard code as well.
