Remote access via GSM using EDGE/3G to standalone ARM

Hi all,
I have an embedded ARM9 system (TS-7800) running with Debian installed far away standalone (so no Wifi, no Ethernet, no PSTN, but mobile cellphone).

How can I sporadically access Internet from this system?
There are some USB modems available offering 3G or EDGE access to the Internet, but almost only drivers for other operating systems and processors.
Do anybody know about a possibility to access Internet via 3G/EDGE from an ARM board running Linux?

Thanks a lot

It should work if the modem works with Linux (you can try on your desktop machine). The software for your Linux desktop and for the ARM-based board is basically the same (but for ARM you'd need to compile it probably). You need the kernel with USB support and pppd daemon. Probably also a dialing tool.
