- increase string space for device class names
- fix the parser so that non-compliant isapnp devices work, and we give up when there are too many errors (some on-board pnp sound/atapi/game soundblaster compatible card). reported by chuck cranor - fix the parser so that configuration tags that come after the end-dependencies tag or before the begin-dependencies tag are merged in properly (gravis ultrasound). reported by gary duzan We now build a tree of card -> logical-dev -> conf, and in the end we convert it to a list of conf...
