You need to use 64 bit kernel if you enable pref64 in LinuxBIOS.

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.
