This is probably a bad entry in the database. The IDE/ISA chip
on your board is probably vt82c576m.

This (a8 20 a8 20 ff 00 ff ff) suggests that the chip could work with
the normal vt82cxxx.c IDE driver. It refuses to do that now, though.
Could you send me the whole lspci -vvxxx, including namely the ISA
bridge? With that knowledge I should be able to make a patch for you
that'll enable your chip in vt82cxxx.c
