[ltp] Required T42/T42p patch for PCMCIA

[Dax Kelson]

After suffering for two months with my T42p not auto detecting inserted
PCMCIA cards (no hotplug events, printks visible with dmesg), and
reproducing the problem on my co-workers brand new T42, I finally found
enough interesting data points (including having PCMCIA hotplug work
when the onboard wired ethernet was up!) to provide a meaningful bug
report.

If your CardBus bridge matches mine:

# lspci | grep CardBus
02:00.0 CardBus bridge: Texas Instruments PCI4520 PC card Cardbus Controller (rev 01)
02:00.1 CardBus bridge: Texas Instruments PCI4520 PC card Cardbus Controller (rev 01)
# lspci -n | grep 02:00
02:00.0 Class 0607: 104c:ac46 (rev 01)
02:00.1 Class 0607: 104c:ac46 (rev 01)

Then you might find that the following patch (for the 2.6 kernel) from
Russell King might help you. It solved all my PCMCIA woes.
