That code was the code author's poor attempt to add VGA routing support for SIMBA based sparc boxes. Unless you're doing some weird multi-head setup, you won't notice if that code is removed. And since it makes the box crash, the code is totally pointless. I disabled it in order to get my ultra5 and ultra10 working. It's amazing that an obvious disk-eater bug with a proposed solution sits in the XORG bug database for months. - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
