They are running a webcam permanently, one is copying from and to a USB floppy in a loop, and I am using a USB mouse on all of them. The issue is that the 0x6x register hack seems to be required for _all_ 96x variants. These come with the 740 as well as all 650 versions, and probably many of the older chips (645, etc), too. Unfortunately, I know of no way how to find out about these south bridges. They have the same PCI ID like the IRQ controller and ISA bridge of the 620, 530, 630 and the old 5595... and partly even the same revision number. Typical SiS stuff, lines up exactly with their graphics hardware... Vojtech recommended doing it like the IDE drivers, but - as I said to him - it feels a bit inappropriate to poke around in the IDE config space for IRQ reasons... But anyone interested should take a look into the newest 5513 ide driver (in the bk tree).
