New SiS 645DX issues (Was: Re: SiS 645DX issues)

[Jeroen]

In just downloaded two new snapshots and the problems seem to have become
more serious:

* the 2CSNAP-20040121-2345 snapshot always hangs at the same point as
reported before, even with dma and write caching disabled
* the dfly-20040118 snapshot reacts non-deterministically: sometimes it
boots with dma and write caching disabled, some times it hangs (again at the
same point as reported before)

I do not understand why this happens. The ata code hasn't changed. Moreover,
this means can't attempt any backporting at the moment, as this makes
installing dfly kind of impossible :-(
