I just bought a new MacBook Pro, and I'm running 10.6.2 and wanted to use my Icon 225 (had previously used it with a Toshiba laptop).
The first fella I spoke to at Orange gave me the wrong advice, and directed me to the standard drivers on the site, which caused the kernel panic for me.
The next fella I spoke to though knew a lot about the problem, and also that they had a more up-to-date solution which isn't yet on the Orange site (!!! I know, jesus...)
Anyway, he directed me to it here -

...I uninstalled the previous drivers, downloaded & installed this, and I'm up and running (using it to post this)
Good luck all.
