I'm lost here, with the factory BIOS IRQs are handled through IOAPIC, but it seems that LinuxBIOS keeps disabling it. I've got both ACPI tables and irq tables (modified to be somewhat correct), and ioapic should be enabled through the vt8237r. The ioapic base seems to be right, and so do all the registers, but there's probably something I'm missing.
What it pretty much boils down to is, what's required to set up APIC/IOAPIC in LinuxBIOS? I've tried using both my vt8237r stuff (originally posted here: http://www.linuxbios.org/pipermail/linuxbios/2007-August/023553.html, cn700 code has changed but vt8237r hasn't for the most part) and with Rudolf Marek's vt8237r_lpc.c (here: http://linuxbios.org/pipermail/linuxbios/2007-July/023023.html). No matter what I do though, LinuxBIOS pops up with this message just before going to the payload:
Disabling local apic...done.
Full boot log, with info from the running system, attached. Any help greatly appreciated, let me know if you need anything else!
