Huawei E220 3G modem drivers on OS X Lion: only 32 bits

I recently installed Mac OS X 10.7 Lion, and found that it already had drivers for the Huawei E220 3G modem. But the drivers are 32 bit, so they won't work for machines which use a 64 bit kernel.

And there seem to be no 64 bits drivers, so the only solution for now is booting in 32 bit kernel mode (pressing 3 and 2 when booting).

I seriously doubt that Huawei are going to publish updated drivers; they were already rather unsupporting even when the modems were new. Eventually, I plan to try to make my own driver, but that won't be short-term...
