SubjectSiS sound driver
Current state of affairs with the SiS/Trident driver tests on this (damn 
annoying) machine.

Any suggestions where to go from here? Recommendations of where to look?
Anything I can test, probe, send the output of? I'm starting to think it's
a PCI addressing problem caused in part by the PnP BIOS. There isn't any
option to disable the PCI PnP BIOS, otherwise I'd have tried that already.
Going to try removing the FireWire expansion and see if that will change
things (by giving me back another interrupt that is).


With 2.4.13: Loads but no sound.
(Fixed the PCI_VENDOR_ID_SI and the device array trailing {0,})

With 2.4.13-ac4: Does not load: "trident: can't allocate I/O space at 0x1000"
(Fixed the PCI_VENDOR_ID_SI)

With 2.4.9: kernel oops.
(Fixed the PCI_VENDOR_ID_SI and the device array trailing {0,})

With 2.4.7: Loads but no sound.
(Fixed the PCI_VENDOR_ID_SI)


All drivers that load produce the following output (well the
version/compile time is different):
Trident 4DWave/SiS 7018/ALi 5451,Tvia CyberPro 5050 PCI Audio, version
