I'm not sure why yet, but this has broken the 5100 - I haven't tried the
3100 yet.  I get to:

	dc0 at ibus0 addr 0x1c000000
	le0 at ibus0 addr 0x18000000: address 08:00:2b:25:28:fc
	le0: 32 receive buffers, 8 transmit buffers
	le0: supplying EUI64: 08:00:2b:ff:fe:25:28:fc
	sii0 at ibus0 addr 0x1a000000: target 7
	mcclock0 at ibus0 addr 0x1d000000: mc146818 or compatible

(but no pm!) and then nothing.  The next line is normally:

	Beginning old-style SCSI device autoconfiguration

backup up to before this, I get

	pm at ibus0 addr 0xfc00000 not configured
	dc0 at ibus0 addr 0x1c000000
	le0 at ibus0 addr 0x18000000: address 08:00:2b:25:28:fc
	le0: 32 receive buffers, 8 transmit buffers
	le0: supplying EUI64: 08:00:2b:ff:fe:25:28:fc
	sii0 at ibus0 addr 0x1a000000: target 7
	mcclock0 at ibus0 addr 0x1d000000: mc146818 or compatible
	Beginning old-style SCSI device autoconfiguration

I'll have a peek at this, but if you've got any ideas, please holler!
Would disabling the badaddr() check be a good place to start?
