1) Will the CF WiFi card work with any of the linux based images?
-> The WiFi part of the card should work. The memory part do not work! And it will only be fixed if you provide kernel patches.
I recomand the i-gate card which i use with wpa.
2) Which image is best for the purposes I have described? I am quite tempted by the Opie image.
-> Angstrom images are a good choice. I personaly use the opie image and like it a lot but the x11 image is also fine.
3) Are the packages kept fairly up to date?
-> Well - yes and no.
The stable branch gets only bugfixes (so the stable image)
The unstable image gets a lot new packages but changes often and also breaks some times!
And no - you cannot mix the unstable/stable feeds
I use the unstable for developing and the stable for daly work. If you like a package backported then you can add it to this list [1]
