Ugh - make sure you aren't using an old acpi-dsdt.aml file. I suggest
following the steps outlined in the SeaBIOS README file for creating a
mybiosdir/ directory and use the QEMU -L option to point to that
directory.
Otherwise...
I compile under FC17. I have pre-packaged binaries available at:
http://code.coreboot.org/p/seabios/downloads/
Also, could you post the log output. Add the following to qemu to
produce it:
qemu ... -chardev stdio,id=seabios \
-device isa-debugcon,iobase=0x402,chardev=seabios ...
Otherwise, we'll need to iterate through each change in the 76e58028
commit and find out which part of the DSDT that your copy of Windows
