We no longer do the blind scan in 2.5.39 and it seems to work fine on
the big sur I tested it on:

	$ uname -v
	#33 SMP Sat Sep 28 10:58:07 PDT 2002
	$ dmesg|fgrep 'Probing PCI'
	PCI: Probing PCI hardware on bus (00)
	PCI: Probing PCI hardware on bus (01)
	PCI: Probing PCI hardware on bus (02)
	PCI: Probing PCI hardware on bus (03)
	PCI: Probing PCI hardware on bus (04)

Could it be that your i2000 has old firmware?  My big sur reports the
following firmware version (via Stephane's smbiosview utility):

	version      : W460GXBS2.86E.0117C.P09.200108091154
