You could write code.  There's documentation available from Via,
but they only automatically give it to companies who are willing
to sign NDA.  They state on their site that they make decisions
on sending technical documentation to Open Source driver writers
"on a case by case basis" (which means they may tell you "no",
even if you are willing to NDA).  You may have better luck with
converting a Linux driver, if there's source available for one
somewhere.

Be aware that if your machine is a "B" (82C686B), then you have
the buggy version of the chip; you need to eiter not use the
second IDE channel for anything, or you need a BIOS update, or
you need to make BIOS advanced settings changes (if your BIOS
supports it, if you have the documentation necessary to make
the changes, if the values are unlabelled in your BIOS, and if
you can find and read the German web site that talks about the
settings).
