From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: This laptop has only a "Win95" or "ACPI" choice in the BIOS for assigning IRQs. Neither seems to improve matters. I tried RH9, and then tried the RawHide 2.4.22 kit as it seems that this card would need ACPI support, which apparently is improved since 2.4.20. I have tried with pci=biosirq on the command line as the syslog message suggests, but there is no improvement.

Some extra musings... based on some google and archived linux-kernel emails out there, notably from Alan Cox - it's my belief that the i810_audio *should* work for SiS 7012, so this isn't a gripe about the driver per se (though it appears that AC has a low opinion of the 7012), but about the (possibly ACPI related) IRQ issues.
Note that acpi is automatically disabled unless you boot with acpi=on
