pccard/cbb problems

I have a ThinkPad 600E laptop on which I can't get the
pcmcia network cards to appear with 5.*.  Tried 5.2.1
stable, now -current, but no dice.  Two card plugged,
a wireless and a wired.  I get some interesting
pccard/cbb errors on boot.  If anyone is currently
working on this and is willing to look at my dmesg
output and tell me what to do to debug, I'd appreciate it.

FYI, the boot oddities are essentially:

module cbb already exists!
cbb/cardbus/pccard inits fine (apparently)
interrupt storm on "irq10: cbb0 cbb1+" - throttled
pccard/cbb reinits and each "card has no functions"

Cheers,

Sam
