I've filed a bug at kernel bugzilla, so your report won't be lost.
See http://bugme.osdl.org/show_bug.cgi?id=4775

In -mm1 the cardbus resources might be assigned in
pci_assign_unassigned_resources() pass. From your dmesg:
PCI: Bus 2, cardbus bridge: 0000:00:0b.0
  IO window: 00002000-00002fff
  IO window: 00003000-00003fff
  PREFETCH window: 12000000-13ffffff
  MEM window: 14000000-15ffffff

Then yenta_allocate_res() tries to assign these resources again and,
naturally, fails.

This adds check for already assigned cardbus resources.

Ivan,
Thank you, it worked.

I have my cardbus + network connection back!  But I still get the 
swag of error messages in syslog.  From cardmgr?  So I mark rc.pcmcia 
non-execute (Slackware) and reboot, I still have cardbus NIC.  

Remove user-space cardmgr, that's what this work was about?  I'll try 
with 16-bit stuff daytime.
