I am getting these messages during bootup time on an IBM Thinkpad T30:

Jul 11 17:17:24 calliope kernel: PCI: Cannot allocate resource region 0
of device 02:00.0
Jul 11 17:17:24 calliope kernel: PCI: Cannot allocate resource region 0
of device 02:00.1

lspci -vv identifies these devices as:

We are also seeing weird PCMCIA behaviour whereby cardmgr does not
detect the insertion and removal of PCMCIA devices. Using the Yenta
socket in the 2.4.18 kernel. Perhaps the boot messages and this
behaviour is related?
