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
