Still doesn't work. I have tried with several kernels and put the dmesg
and lspci logs here:

Some things I have noticed (diff from -pre5 to -pre6):

-Booting processor 1/1 eip 2000

-pre6 does not detect IRQ26-31 (second APIC?). And pre5 used them:

PCI: PCI BIOS revision 2.10 entry at 0xfdbb1, last bus=1
PCI: Using configuration type 1
PCI: Probing PCI hardware
PCI: Probing PCI hardware (bus 00)
PCI: Discovered primary peer bus 01 [IRQ]
PCI: Using IRQ router ServerWorks [1166/0200] at 00:0f.0
PCI->APIC IRQ transform: (B0,I6,P0) -> 31
PCI->APIC IRQ transform: (B1,I2,P0) -> 26

Booting with pci=noacpi just hangs the booting process.

Any ideas ?
