If you control whole stack, nothing is really unfixable, you will just
need more effort :-)

Also this requires some code in WebKit (more below) so it should be fixable.

Last time I touched this code (which was several years ago), the
network code needed to be aware of the custom methods. That means that
when you create the low-level library representation of an HTTP
request, you need to take into account
ResourceRequestBase::m_httpMethod. As you didn't tell us which port
you are building (see http://www.webkit.org/asking_questions.html), my
wild guess is that your platform doesn't support that. I don't know of
any configuration option for that as I would expect this to be core to
any network stack if it is implemented (as you didn't tell us much
details, I could be completely wrong though).

Btw, you can also check the support of your port locally as we have 2
tests covering this area:
* LayoutTests/fast/http/tests/xmlhttprequest/methods.html
* LayoutTests/fast/http/tests/xmlhttprequest/methods-async.html
