unable to remove socket power / 2.6.13-rc3-mm2 / TP 600X

I still get 'unable to remove socket power'.

Here is the dmesg error, which happens after 'cardctl eject' with the
Intersil (or my Xircom) card in the slot:

  PCMCIA: socket e233c02c: *** DANGER *** unable to remove socket power

I don't think it's the same problem described in the known problems
section of
<http://kernel.org/pub/linux/utils/kernel/pcmcia/pcmcia.html>.  For one,
I'm usin 2.6.13-rc3-mm2, and the problem described on that page should
be fixed in 2.6.11.  Also, the BIOS RAM map doesn't have any holes in
the physical RAM, and lspci -vv doesn't show the Cardbus bridge grabbing
any such illegal ram anyway.

I'm happy to send more debugging information or try tests.  Below is
hopefully useful information.  Since this involves the in-kernel
pcmcia-cs, should I send this to LKML as well (or put it on the
bugzilla)?
