The patch didn't help, but commenting out SB_HT_CHAIN_ON_BUS0 did. Now
the SB is on bus 1 and the devices are getting initialized only once.

Any idea what those "Unable to handle 64-bit address space for bridge
0000:01:03.0" errors are about? The stuff about IO/MEM/PREFETCH
windows being disabled doesn't look good either.

I suppose the first order of business is to get interrupts going, though.
