Can you check if the IRQ allocated to the SiS900 is the same on kernels
where it does work, and try without ACPI support, and/or any IO-APIC support
disabled?

I've seen this before with the network card in one of my systems - the
IO-APIC setup code, or ACPI table parsing was misprogramming the IRQ routing
tables, and it was being allocated the wrong level-triggered IRQ line.
