This is really strange; siop_pci_attach is a 3 line function.
Can you confirm with gdb where it is ?
On my kernel gdb says that siop_pci_attach+0x28 is at the closing brace of
the funtion. I have a 53c875 in my machine:
siop0 at pci1 dev 1 function 0: Symbios Logic 53c875 (ultra-wide scsi)
siop0: using on-board RAM
siop0: interrupting at ivec 10
scsibus0 at siop0: 16 targets, 8 luns per target

Can you try to boot a kernel without siop to see what PCI vendor/device
ID this adapter has ?
Also, maybe add a few printfs in siop_pci_attach and siop_pci_attach_common
to narrow down the place where the kernel dies.
