Answers
  • I have an external unlocked 3G modem board that works great with 2.6.24. Found it on ebay for $25. I think it counts as a mini-pci express bridge because the mini-pci express cellular modem it takes appears as though it would on a laptop.

    Normally those cell modems show up as two usb serial ports accepting AT commands. One is for communication, and the other one is so you can query modem status information (signal, etc)

  • I'm using OpenWRT kamikaze 8.09 version with few embedded boards and Access points as well, I'm connecting huawei E220 USB HSDPA cards and they're working without troubles.
    Currently using different kernels but 2.6.25, 2.6.27 have no problems with it, by the way I don't think 2.6.24 and other kernels can cause troubles to your modem.
    Tell us something more about your embedded device, your toolchain and devel environment or linux distro if you're using something more widespread.
    Don't think the kernel is the problem, maybe something about your config or your local devel environment, if you look at OpenWRT or other embedded distros you'll see they (we) are using these modems

  • Although the E220 has been configured for Linux, I can't say for sure that it's because of the support of Huawei.

    Vodaphone paid for and open-sourced research for Linux drivers for their HSDPA, so you might consider the Vodaphone:

    From [url]linux-drivers.org[/url]:

    is a software suite for the mobile 3G datacard which works on multiple distributions of the Linux Operating System.
