82801DB* (ICH4*) actually (see lspci), 82801 is too generic.

Northbridge is i845, which is not yet supported, so supporting the board
is not trivial. We have to add i845 (RAM init and other stuff) support
first. This might happen sooner or later, but if you want to use
coreboot on some hardware very soon I recommend getting an
already-supported board.

ICH4 is supported in the i82801xx code, that part it OK.

This is the BIOS chip rather.

This one is the Super I/O. No support per se (and I can't find a
datasheet at the moment), but most important here is that we can
enable serial COM ports in the Super I/O, which we should be able
to guess and test based on other SMSC Super I/Os.

You BIOS chip is detected by flashrom, though it's marked as untested in
your flashrom version (which seems to be pretty old, please update to
latest svn if possible).

Whether or not writing the chip in this board will actually work cannot
be said easily, you'll have to test that (make sure you have a working
backup chip before doing that).
