"PCI: Cannot allocate resource region" messages at boot

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?

I had a similar problem on my notebook, but this patch seems to fix it:

 	min = PCIBIOS_MIN_MEM; max = ~0U;
 	if (type & IORESOURCE_IO) {
 		align = 1024;

I have no idea if this is the right thing to do. I found the suggestion in an earlier message from Andreas Bombe.

I tried it out but the patch doesnt seem to make any difference.

I see those messages before any attempt to load the yenta/pcmcia socket models. It has to be something else, I would think. Following is the sequence of messages at boot time (the messages appear whether or not I load pcmcia modules):

Thanks for the suggestion though.
