Hey ladies! I bought a Texas Instrument bases ExpressCard for Firewire 400 in order to make my RME Fireface work on the late 2008 MBP (the onboard LSI/Agere chip doesn't like the Firefaces). Result: It made OS X freeze out of the blue several times and it is not possible to install it on bootcamped Vista at all: "Not enough free Resources". I did some web search and found a post of someone who tried six (6!) different ExpressCards and all showed the same "no free resources" error when using Bootcamp. So currently I am left with a Pro laptop that comes with incompatible Firewire and unuseable ExpressCard. Fortunately the Fireface is useable via any Fireface Repeater: external HD, HUB, or in my case a simple Repeater Cable (aka cable with inbuild repeater). Time to call Apple support I guess!
