I turned on all the PCIBIOS FIXUP/VERBOSE defines, and also
PCMCIA{CIS,}DEBUG.  There are some 'vcc request' problems, and
1) wi (pcmcia) still gets no response
2) cardbus cards are recognized (or not, depending on drivers), but
initialization fails, with 'bad Vcc' messages.

I found a manual from Sycard Technology:
  http://www.sycard.com/aftp/man460f.pdf
On page 29 (Appendix C1) it discusses some odd power control behavior
of TI PCI12xx chips:

  Texas Instrument's latest series of socket controllers supports a
  serial controlled voltage switch to control the Vcc and Vpp to the PC
  Card socket. Three signal lines, DATA, CLOCK and LATCH are used to
  control the outputs of the voltage switch. On TI s PCI12xx/14xx/44xx
  demo boards, the CLOCK is configured as an output from the socket
  controller. However, in some implementations the CLOCK signal is
  externally generated and is an input to the PCI12xx socket
  controller. A control bit in PCI configuration space address 80H
  called P2CCLK (Bit 27) enables the voltage switch clock output (CLOCK)
  from the CardBus controller chip. CLOCK is derived from the PCI
  clock. In the original PCCtest software, this bit was set to enable
  CLOCK as an output. This was required for the PCI12xx/14xx demo
  boards. Designs that have an externally generated CLOCK will see two
  sources driving the CLOCK signal when running the PCCtest software.

I found a linux patch that seems to fit this theory:

http://pcmcia-cs.sourceforge.net/cgi-bin/HyperNews/get/pcmcia/install/12/1.html?nogifs
and the man page for using a variable to control clock setting:
http://pcmcia-cs.sourceforge.net/man/i82365.4.html

Does anyone have a PCI12xx-based laptop that works with cardbus?

Does it seem plausible that the IBM 600E needs the P2CCLK bit turned
on to work?

Complete 'boot -v' dmesg of kernel with all the debug/verbose options,
annotated with what cards I inserted, followed by pcictl dump of the
bridge.
