Not really, I've never done that.
| | | | You know, it's possible that you could purchase a card that already | | | | works on Linux 2.6.... that might be a better solution than trying | | | | to use an unknown binary module. | | | | Well, Sam Ravnborg did post a patch in the last week or so that | | should help with (some) binary files... probably .o and not .bin, | | or maybe it doesn't matter. | | | | Clarify please. A patch to kbuild? Or to the kernel? Note that the .bin | file is only the card firmware. No point looking in that for anything. | The binary part of the _driver_ is in nokia_cs.a, which contains .o files.
A patch to kbuild (the kernel makefile system).
You would need to read Sam's emails about this to see how it works.
| | | At this point I am doing this just to see if it will work... I don't | | | need the card for another week or so and if I don't get this one to work | | | I'll just buy another one.

Sorry, I have no idea.
