The best thing to do may be to take a look at what the bootloader serial
driver does and what the in-kernel serial driver does.

The in-kernel serial driver is here:

platform/s3c2410/pistachio/kdb/console.cc

I should be able to produce you an image which works on the OpenMoko.
But it appears the problem is not with the binary generation but more
so that there is a problem with the serial driver.

By the way, the OKL4 list is developer at okl4.org.  If you sent privately
you miss out on the opportunity for others, who may have seen this
problem before, to help you.
